Answers

Answer 1

Answer:

Nitrogen is a chemical element with an atomic number of 7 (it has seven protons in its nucleus). Molecular nitrogen (N2) is a very common chemical compound in which two nitrogen atoms are tightly bound together. Molecular nitrogen is a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures.

Explanation:

i had this quest before but it might be different 4 u tho.:)))))))

Answer 2

With seven protons in its nucleus, nitrogen has the atomic number 7 and is a chemical element.

Thus, Two nitrogen atoms are securely linked together to form the chemical molecule known as molecular nitrogen. At normal temperatures and pressures, molecular nitrogen is a colorless, odorless, tasteless, and inert gas.

Numerous different forms of contaminants contain atoms of nitrogen. Nitric oxide and nitrogen dioxide can be produced during high temperature combustion when nitrogen gas is present, as in car engines.

Both gases contribute to the creation of nitric acid, which is a component of acid rain, and peroxyacetyl nitrate (PAN), which is a key component of smog.

Thus, With seven protons in its nucleus, nitrogen has the atomic number 7 and is a chemical element.

Answers

On increasing the temperature of a reaction, there is an increase in the reaction rate. Thus Option A is the answer.

On increasing the temperature of a reaction, the effective collisions between the reactants increases. The particles move faster and so they collide more frequently, increasing energy, thus making the reaction rates faster.

For rough approximation, the rate of reaction doubles for every 10°C rise in temperature.

On the contrary, by decreasing the temperature, speed of particles decreases thus its energy and therefore the reaction rates are slower.

Any factor that increases the Collison rate definitely increase the rate of reaction, concentration, temperature, surface area, pressure and catalyst are the major factor that affect the rate of reaction. Therefore, the correct option is option A.

What is rate of reaction?

The rate of reaction is the study of change of concentration of reactant or product with respect to time.

There are so many factors that affect the rate of reaction

1)concentration: As the concentration of reactant increases the number of collisions increases so rate of reaction also increases.

2)temperature: As the temperature increases the movement of gaseous molecule increases hence the Collison rate increases and hence the rate.

3)surface area (for solid reactants ONLY): As the surface area of the catalyst increases, more molecule can sit on the reactive site hence more is the rate of reaction.

4)pressure (for gaseous reactants ONLY): As pressure increases the randomness increases and hence the Collison and hence the rate of reaction

5)catalyst: Catalyst increase the rate of reaction as they decrease the activation energy

Therefore, the correct option is option A.

Answers

Answer:

The empirical formula is the simplest form;

Given:

Oxygen O at 94.1% and

H at 5.9%

Assume 100grams.

94% = 0.941 x 100gm. = 94.1 gm x 1mole/16gm. = 5.88 moles of O

5.9% = 0.059 x 100gm. = 5.9gm. X 1moleH/1.002gm. = 5.88 moles of H

There is one mole of O for each mole of H so the empirical formula is \(O_1H_1\)

Answers

The mass percent of the solution is approximately 10.51%.

To calculate the mass percent of the solution, we need to determine the total mass of the solution.

The mass of the solution can be calculated using the density and volume of the solution:

Mass of the solution = Density × Volume

Mass of the solution = 1.06 g/ml × 895 ml

Mass of the solution = 948.7 g

The mass percent of the solution can be calculated by dividing the mass of the solute (CSI) by the mass of the solution and multiplying by 100:

Mass percent = (Mass of CSI / Mass of the solution) × 100

Mass percent = (99.7 g / 948.7 g) × 100

When hydrochloric acid is passed through a saturated solution of common salt, a precipitate of _______ will form. ​

Answers

When hydrochloric acid (HCl) is passed through a saturated solution of common salt (NaCl), a precipitate of sodium chloride (NaCl) will form.

This reaction occurs due to a chemical reaction between the hydrochloric acid and the sodium chloride in the solution. Hydrochloric acid is a strong acid that dissociates into hydrogen ions (H+) and chloride ions (Cl-) in water. When it is added to a saturated solution of common salt, which already contains dissolved sodium ions (Na+) and chloride ions (Cl-), a precipitation reaction takes place. The hydrogen ions from the acid combine with the chloride ions from the salt solution to form hydrochloric acid molecules (HCl) again.

The remaining sodium ions and chloride ions in the solution are now in excess, causing the solubility of sodium chloride to be exceeded. As a result, solid sodium chloride particles begin to form and settle as a precipitate in the solution. This precipitation reaction is a common occurrence when mixing hydrochloric acid with a saturated solution of common salt.

The formed precipitate of sodium chloride appears as fine crystals or solid particles, depending on the concentration of the salt solution and the amount of hydrochloric acid added. These particles can be separated from the solution through filtration or other appropriate techniques.

In summary, when hydrochloric acid is passed through a saturated solution of common salt, a precipitate of sodium chloride will form due to the chemical reaction between the acid and the salt solution.

what is the heat of formation (deltahf) per mole of hydrogen fluoride? what is the h-f bond strength?

Answers

The heat of formation (ΔHf) per mole of hydrogen fluoride is -273.3 kJ/mol while the H-F bond strength is 567.3 kJ/mol.

The heat of formation (ΔHf) is the enthalpy change that accompanies the formation of one mole of a substance from its constituent elements. This value is negative for exothermic reactions, which are spontaneous, and positive for endothermic reactions, which are non-spontaneous. When hydrogen fluoride is formed from hydrogen and fluorine, heat is released, resulting in a negative ΔHf value. The heat of formation of hydrogen fluoride per mole can be calculated using the following equation:

2H2(g) + F2(g) ⟶ 2HF(g)ΔHf = -273.3 kJ/mol

The H-F bond strength is the amount of energy required to break one mole of H-F bonds. This value can be calculated using the following equation:

HF(g) ⟶ H(g) + F(g)ΔH = 567.3 kJ/mol

In other words, the H-F bond strength is the enthalpy change that accompanies the dissociation of one mole of hydrogen fluoride into its constituent atoms. The energy required to break the bond between hydrogen and fluorine is 567.3 kJ/mol, which is a measure of the strength of the bond.

Answers

An expression for the expansion coefficient, a, and the isothermal compressibility, KT of a perfect gas as a function of T and P, respectively is  KT = -(1/V) * (∂V/∂P)T.

To derive the expression for the expansion coefficient, a, and the isothermal compressibility, KT, of a perfect gas as a function of temperature (T) and pressure (P), we start with the ideal gas law:

PV = nRT,

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

We can differentiate this equation with respect to temperature at constant pressure to obtain the expression for the expansion coefficient, a:

a = (1/V) * (∂V/∂T)P.

Next, we differentiate the ideal gas law with respect to pressure at constant temperature to obtain the expression for the isothermal compressibility, KT:

KT = -(1/V) * (∂V/∂P)T.

By substituting the appropriate derivatives (∂V/∂T)P and (∂V/∂P)T into the above expressions, we can obtain the final expressions for the expansion coefficient, a, and the isothermal compressibility, KT, of a perfect gas as functions of temperature and pressure, respectively.

Note: The specific expressions for a and KT will depend on the equation of state used to describe the behavior of the gas (e.g., ideal gas law, Van der Waals equation, etc.).

Answers

Three eluents in order of increasing polarity: hexane (least polar), ethyl acetate (moderately polar), and methanol (most polar).

Developing the plate in an uncovered chamber can lead to evaporation of the eluent, altering its composition and potentially affecting the separation of the compounds.
The choice of eluent depends on the polarity of the compounds being separated. If you selected ethyl acetate, it's likely because it provides optimal separation for your specific mixture. Hexane may not provide sufficient separation due to its low polarity, while methanol could be too polar, causing compounds to move too quickly and not separate properly.
Effects of procedural errors:
Spotting too much sample on the plate can lead to poor resolution and overlapping spots, making it difficult to analyze the results.
Placing the spotted plate into a chamber containing eluent at the origin can cause the sample to dissolve immediately, affecting the separation and resolution.
Allowing the plate to remain in the chamber until the eluent front reaches the top of the plate can result in poor separation, as all compounds may migrate with the solvent front.
Removing the plate when the eluent front has moved only halfway up the plate may provide insufficient separation and incomplete analysis of the components.

(b) What is the value of the standard deviation Delta*x in the internuclear distance? (c) What is the standard deviation Delta*p_{x} of the momentum of the vibrational motion? (d) Check that the product Delta*x*Delta*p_{x} yields hbar/ 2 in accordance with the Heisenberg uncertainty principle.

Answers

A- The value of force constant is 1.98 x \(10^3 N/m.\), B-the value of standard deviation is  4.53 x \(10^{12} m\), C-  the standard deviation in the momentum of the vibrational motion is at least 1.16 x \(10^-23 kg m/s.\)

(a) The vibration frequency of the molecule is given as 2170. We can relate the force constant k and the vibration frequency by the following equation: ν = (1/2π) √(k/μ)

We can rearrange this equation to solve for k:

k = 4πμ\(v^{2}\)

The molecular weight of 12C^16O is approximately 28 atomic mass units (amu), and the molecular weight of one atomic mass unit is approximately 1.66 x \(10^-27 kg\). Therefore, the reduced mass of the molecule is:

μ = m_C * m_O / (m_C + m_O) = (12 amu * 16 amu) / (12 amu + 16 amu) * ( 1.66 x \(10^-27 kg\). amu) = 1.15 x\(10^-26\) kg

Substituting the values of μ and ν into the equation for k, we get:

k = 4π^2 * 1.15 x  \(10^-26\)kg * (2170 cm^-1) = 1.98 x\(10^3\) N/m

\(10^3 N/m.\)

(b) The standard deviation Δx in the internuclear distance can be calculated using the following equation:

Δx = √(hbar / 2μω)

where hbar is the reduced Planck constant (1.0546 x 10^-34 J s), μ is the reduced mass of the molecule, and ω is the angular frequency of the vibration (2πν).

Substituting the values, we get:

Δx = √(1.0546 x\(10^-34\) J s / (2 * 1.15 x\(10^{26\) kg * 2π * 2170 s)) = 4.53 x \(10^{12} m\)

(c) According to the Heisenberg uncertainty principle, the product of the standard deviations of the position and momentum of a particle in a particular direction must be greater than or equal to hbar/2:

Δx * Δp_x >= hbar/2

We can solve for Δp_x:

Δp_x >= hbar / (2Δx)

Substituting the values, we get:

Δp_x >= 1.0546 x\(10^{34 }\)J s / (2 * 4.53 x \(10^-12\) m) = 1.16 x \(10^{-23\) kg m/s

(d) The product of the standard deviations of the position and momentum should yield hbar/2, in accordance with the Heisenberg uncertainty principle:

Δx * Δp_x = hbar/2

Substituting the values, we get:

( 4.53 x \(10^-12\) m) * 1.16 x \(10^{-23\) kg m/s =1.0546 x\(10^{34 }\)J s / (2

Non-metals will quite often acquire electrons more promptly than metals because of their higher electronegativity, making them bound to go about as oxidizing specialists.Metals, then again, will quite often lose electrons and are bound to go about as decreasing specialists in a redox response.

A and B are two imaginary substances. The molecules of substance A have weak electrical forces between them. The
molecules of substance B have very strong electrical forces linking them. Which boils at a lower temperature?

Substance A
It is impossible to know
Substance B

Answers

I believe the answer is A, if they have a stronger connection lower the vapor pressure so higher the boiling point

A and B are two imaginary substances. The molecules of substance A have weak electrical forces between them. The molecules of substance B have very strong electrical forces linking them. Substance A boils at a lower temperature.

Boiling is the process in which a liquid changes into a gas at its boiling point, which is the temperature at which its vapor pressure equals the atmospheric pressure. The boiling point of a substance is influenced by various factors, including the strength of the forces between its molecules.

In substance A, the molecules have weak electrical forces between them. These weak intermolecular forces imply that the molecules are not strongly attracted to each other. As a result, less energy is required to break these weak forces, and the substance can transition from a liquid to a gas more easily. Therefore, substance A will have a lower boiling point compared to substance B.

In substance B, the molecules have very strong electrical forces linking them. These strong intermolecular forces indicate that the molecules are strongly attracted to each other. Consequently, more energy is required to overcome these strong forces during the boiling process, making the substance have a higher boiling point.

Therefore, substance A, with weak intermolecular forces, would boil at a lower temperature, while substance B, with very strong intermolecular forces, would boil at a higher temperature.
