2. Precipitation Reaction

Explanation:

Na3PO4(aq) + FecCl2(aq) = Fe3(PO4)2(s) + NaCl(aq)

Fe3(PO4)2(s) - solid, it means it will precipitate.

It is a precipitation reaction.

A precipitate is a solid that forms out of a solution. A common example is that of the mixing of two clear solutions: (1) silver nitrate (AgNO3) and (2) sodium chloride (NaCl): The reaction is. The precipitate forms because the solid (AgCl) is insoluble in water.

A precipitate is a solid formed in a chemical reaction that is different from either of the reactants. This can occur when solutions containing ionic compounds are mixed and an insoluble product is formed. The identity of the precipitate can often be determined by examining solubility rules.

Answer:

760 mm of Hg

Explanation:

If the gases A , B and C are non reacting , then according to Dalton's Law of Partial Pressure the total pressure exerted is equal to sum of individual partial pressure of the gases .

If there are n , number of gases then ,

\( P_{total}= P_1+P_2+P_3+\dots +P_n\)

Here ,

Hence the total pressure exerted is ,

\( P_{total}= P_{Gas\ A }+P_{Gas\ B }+P_{Gas\ C }\)

Substitute ,

\(P_{total}=( 400 + 220 + 140 )mm\ of \ Hg \)

Add ,

Answer:

This process is called mass spectrometry. In mass spectrometry, a sample is ionized, typically by bombarding it with high-energy electrons, and the resulting ions are separated based on their mass-to-charge ratio. The mass of the ions can be measured using a mass spectrometer, and this allows the determination of the atomic masses of the elements present in the sample. To obtain accurate results, it is generally necessary to measure the masses of a large number of atoms, as the precision of the measurement increases with the number of atoms that are measured

At equilibrium, the system will move to the right to regain equilibrium

Based on the percentage mass of oxygen in trifluoroacetic acid, the mass of the trifluoroacetic acid sample is 168.5 grams.

The percentage mass of oxygen in trifluoroacetic acid is determined as follows:

The molar mass of trifluoroacetic acid = 12 * 2 + 1 + 19 * 3 + 16 * 2

The molar mass of trifluoroacetic acid = 114 g

The percentage mass of oxygen in trifluoroacetic acid = (16 * 2)/114 * 100%

The percentage mass of oxygen in trifluoroacetic acid = 28.07%

The mass of the trifluoroacetic acid sample will be 47.3/ 28.07% = 168.5 grams

Ethanol (C2H6O), an alcohol has a much higher boiling point than dimethyl ether (C2H60) because hydrogen bonds found in the former are typically much stronger attractions than ordinary dipole moments in the latter.

This is referred to as the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.

Ethanol (C2H6O), an alcohol has a much higher boiling point than dimethyl ether (C2H60) because hydrogen bonds have a stronger attraction which  makes it more difficult for the atoms to be broken down hence the reason why the boiling point will be higher in this scenario.

The statement that is not part of Dalton's atomic theory is that atoms are composed of protons, neutrons, and electrons.

This statement is not part of Dalton's atomic theory because the existence of subatomic particles such as protons, neutrons, and electrons was not discovered until much later, after Dalton's time.

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below.

The molar concentration of the salt is  0.600 M. Option B

We know that the term molar concentration has to do with the number of moles of the salt that is present in one liter of the solution. We have been given the mass of the salt that is formed, we need to obtain the number of moles of the salt that has been formed and use the volume of the solution that have been given in the question to find the molar concentration of the salt.

Mass of the salt = 8.24 g

Molar mass of the salt = 58.5 g/mol

Number of moles of the salt = mass/molar mass

=  8.24 g/ 58.5 g/mol

= 0.14 moles

Volume of the solution = 235.0 mL or 0.235 L

Molar concentration =  0.14 moles/ 0.235 L

= 0.595 M or  0.600 M

Answer:

1.209g of MgO participates

Explanation:

In this problem, we have 0.030 moles of MgO that participates in a particular reaction.

And we are asked to solve for the mass of MgO that participates, that means, we need to convert moles to grams.

To convert moles to grams we need to use molar mass of the compound:

1 atom of Mg has a molar mass of 24.3g/mol

1 atom of O has a molar mass of 16g/mol

That means molar mass of MgO is 24.3g/mol + 16g/mol = 40.3g/mol

The reactions that result in the emission of light involve the ruthenium label and tripropylamine (TPA), two electrochemically active molecules.

Thus, The electrode surface inside the measurement cell is where the reactions take place.

The ruthenium label is oxidized at the electrode surface as an electrical potential is applied, and TPA is oxidized into a radical cation that spontaneously loses a proton.

When the resultant TPA radical interacts with oxidized ruthenium, the ruthenium label enters an excited state and emits a photon (620 nm) before decaying. The ruthenium label is renewed and ready to carry out numerous light-generating cycles as it goes back to its ground state.

Thus, The reactions that result in the emission of light involve the ruthenium label and tripropylamine (TPA), two electrochemically active molecules.

Answer: A physical property that will be the same regardless of the amount of matter. Extensive Properties:  A physical property that will change if the amount of matter changes.

The pOH of the 0.001 M NaOH solution is approximately 3.

To determine the pOH of a solution, we need to know the concentration of hydroxide ions (OH-) in the solution.

In the case of a 0.001 M NaOH solution, we can assume that all of the NaOH dissociates completely in water to form Na+ and OH- ions. Therefore, the concentration of hydroxide ions in the solution is also 0.001 M.

The pOH is calculated using the equation:

pOH = -log[OH-]

Substituting the concentration of hydroxide ions, we have:

pOH = -log(0.001)

Using a calculator, we can evaluate the logarithm:

pOH ≈ 3

Therefore, the pOH of the 0.001 M NaOH solution is approximately 3.

Substituting the given values, we have (0.5 L) / (220 + 273.15 K) = V₂ / (313.15 K).Solving for V₂, we get V₂ = (0.5 L) * (313.15 K) / (220 + 273.15 K).

Calculating this expression, the volume of the balloon when fully cooled by your refrigerator would be approximately 0.38 liters when rounded to two decimal places.To convert Celsius to Kelvin, we need to add 273.15 to the Celsius temperature. Therefore, the temperature inside your refrigerator of 40 degrees Celsius is equivalent to 313.15 Kelvin.Now, let's consider the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.Since the number of moles and pressure remain constant, we can write  the equation as V₁/T₁ = V₂/T₂, where V₁ is the initial volume of the balloon, T₁ is the initial temperature, V₂ is the final volume, and T₂ is the final temperature.

The final temperature of water and aluminum will be 27.2 °C., after they are allowed to come to thermal equilibrium.

Here,

a)  According to first law of thermodynamic the energy is conserved.

b)  In an insulated system there is no loss of heat

So, Heat lost by aluminum will be equal to heat gained by water

c)  At thermal equilibrium the, final temperature of water will be equal to final temperature of aluminium

Formulae:

Heat gain or loss = m×Cs×ΔT,

where m = mass of the substance,

Cs is the specific heat of the substance,

ΔT is the change in temperature

mass of  aluminum, Ma = 15.7g

Temprature of aluminium  = 53.2 °C

mass of  water, Mw = 32.5 g

Temrature of water= 24.5°C

Known values:

Specific heat liquid water: Cs = 1 cal/g°C

Specific heat aluminum: Cs = 0.215 cal/g°

So Calculation will be done,

Heat of aluminium = Heat of water

Heat of water = m Cs ΔT = 32.5g × 1× (T - 24.5)

Heat of aluminium = m  CsΔT = 15.7× (0.215) (53.2 - T)

32.5 (1 ) (T  - 24.5) = 15.7 (0.215) (53.2 - T)
