2 C4H10 + 13 O2 → 8 CO2 + 10 H2O.

Answer:

\(\boxed {\boxed {\sf B. \ 22 \ grams}}\)

Explanation:

We need to use the formula for heat of vaporization.

\(Q=H_{vap}*m\)

Identify the variables.

\(H_{vap}=2260 \ J/g\\Q=50,000 \ J \\\)

Substitute the values into the formula.

\(50,000 \ J=2260 \ J/g*m\)

We want to find the mass. We must isolate the variable, m.

m is being multiplied by 2260 J/g. The inverse operation of multiplication is division. Divide both sides by 2260 J/g.

\(\frac{50,000 \ J}{2260 \ J/g} =\frac{2260 \ J/g*m}{2260 \ J/g}\)

\(\frac{50,000 \ J}{2260 \ J/g} =m\)

Divide. Note that the Joules (J) will cancel each other out.

\(\frac{50,000 \ }{2260 \ g} =m\)

\(22.1238938 \ g =m\)

Round to the nearest whole number. The 1 in the tenth place tells us to leave the number as is.

\(22 \ g \approx m\)

The mass is about 22 grams, so choice B is correct.

Mass = 917.4 g

Explanation:

Given data:

Number of molecules = 3.00 ×10²⁴ molecules

Mass in gram = ?

Solution:

Explanation:

I hope this helps!

The molar mass and molecular weight of C3H6(OH)2 is 76.0944.

Explanation:

Mole Ratio of O₂ : NO

Based on the balanced equation, the mole ratio of O₂ : NO is 5 : 4

∴ for every mole of O₂ reacted, ⁴/₅ moles of NO is produced

Moles of NO

since the number of mol of O₂ =  2.0 mol

   then moles of NO produced = 2.0 mol × ⁴/₅

                                                   =  1.6 mol

∴ the moles of nitrogen monoxide that will form if we start with 2.0 moles of oxygen is 1.6 mol (option 5).

Answer:

solid=(s)

Explanation:

A solubility table may be something your class may want you to memorize. Where an aqueous (aq) solution is formed by a soluble compound dissolving in water, our solvent. So if we refer to this solubility table, it says phosphate (PO4) is usually insoluble, so in the reaction it won't break down in water and will stay as a solid (s). The only exceptions are group 1 alkali metals or ammonium (NH4+).

Answer:The bigger the atom the lesser the ability of the atom to hold on to its valence electrons.

Explanation:

The larger the atom, the lesser the tendency for the atom to withhold its valence electrons.

The size of an atom is usually estimated in terms of its atomic radius. Across the period in the periodic table, the atomic radius decreases progressively from left to right. This is due to the progressive increase in the nuclear charge (i.e., the number of protons in the nucleus) without an attendant increase in the number of electron shells.

Similarly, down the group, the atomic radius increases progressively from top to bottom due to the successive number of electrons' shells.

Thus, the larger the atom's radius, the smaller the Ionization energy because of the increasing shielding effect of inner shell electrons on the electron to be removed from the nuclear attraction.

Finally, we can conclude that as the atom becomes larger, the tendency to withhold the electrons on the outer shell decreases due to distance and the shielding/ screening effect.

The range of vapor pressures in different liquids at the same temperature can be explained in terms of entropy and enthalpy. Liquids with weaker intermolecular forces tend to have higher vapor pressures due to higher entropy, while liquids with stronger intermolecular forces tend to have lower vapor pressures due to lower enthalpy.

Different liquids have widely differing vapor pressures at the same temperature due to variations in their intermolecular forces and the degree of dispersal between the liquid and gaseous states.

The vapor pressure of a liquid is the pressure exerted by its vapor when it is in equilibrium with its liquid phase at a given temperature. It depends on the attractive intermolecular forces between the molecules and the extent to which the liquid molecules can escape into the gas phase.

1. Entropy: Entropy is a measure of the disorder or randomness in a system. Liquids with weaker intermolecular forces have higher entropy because the molecules are more free to move and disperse. These liquids tend to have higher vapor pressures at a given temperature because the molecules can more easily overcome the attractive forces and enter the gas phase.

2. Enthalpy: Enthalpy is a measure of the total energy of a system. Liquids with stronger intermolecular forces have lower enthalpy because more energy is required to break the attractive forces and convert the liquid into a gas. These liquids tend to have lower vapor pressures at a given temperature because fewer molecules can overcome the attractive forces and enter the gas phase.

For example, consider two liquids: water and ethanol. Water has strong hydrogen bonding between its molecules, resulting in lower entropy and higher enthalpy. As a result, water has a lower vapor pressure at a given temperature compared to ethanol, which has weaker intermolecular forces. Ethanol has higher entropy and lower enthalpy, allowing more molecules to escape into the gas phase and resulting in a higher vapor pressure.

The time required to complete the reaction by 75% is approximately 51.3 minutes.

The half-life of a first-order reaction is a constant value that is independent of the initial concentration of the reactant. It is given by the equation:

t1/2 = ln(2) / k

where t1/2 is the half-life, ln(2) is the natural logarithm of 2 (approximately 0.693), and k is the rate constant for the reaction.

We can use the given information to determine the rate constant k:

t1/2 = 30 minutes

ln(2) / k = 30 minutes

k = ln(2) / 30 minutes ≈ 0.0231 min^-1

Now we can use the rate constant to determine the time required to complete the reaction by 75%:

ln(Ct / Co) = -kt

where Ct / Co is the fraction of reactant remaining at time t, Ct is the concentration at time t, Co is the initial concentration, and k is the rate constant.

For 50% completion, Ct / Co = 0.5:

ln(0.5) = -0.0231 min^-1 * t

t ≈ 30.1 minutes

For 75% completion, Ct / Co = 0.25:

ln(0.25) = -0.0231 min^-1 * t

t ≈ 51.3 minutes

Therefore, the time required to complete the reaction by 75% is approximately 51.3 minutes.

The three ways thermal energy is transferred are;

1) Conduction

2) Convection

3) Radiation

Explanation:

1) The conduction of the heat from the open flame to the marshmallow is through the direct contact of the flame with the marshmallow, such that the flame the region of the combustion reaction, that produces light and heat touches the marshmallow

2) The convection process is the transfer of heat from the rising heated combustion products, as well as the heated air that rises from the flame

3) The radiation heat transfer is the transfer of the heat from the fire to the marshmallows directly by the heat the moves in the form of electromagnetic waves at temperatures above 1000 K, without the need for a medium, such that the marshmallow can be heated by the heat coming from side of the flame.

We know that there are two isotopes of copper: 63Cu and 65Cu, with the given atomic masses and an average mass of 63.546 amu.

Average atomic mass of copper = (mass of 63Cu x % abundance of 63Cu) + (mass of 65Cu x % abundance of 65Cu)63.546 amu

= (62.9296 amu x % abundance of 63Cu) + (64.9278 amu x % abundance of 65Cu)

We are given that the atomic mass of 63Cu is 62.9296 amu and that of 65Cu is 64.9278 amu, so we can substitute these values and rearrange the equation to solve for % abundance of 63Cu.

% abundance of 63Cu = (63.546 amu - 64.9278 amu x % abundance of 65Cu) / (62.9296 amu)

0.5 amu = (64.9278 amu x % abundance of 65Cu) / (62.9296 amu)0.5 x 62.9296 amu

= 64.9278 amu x % abundance of 65Cu31.4648 amu

= 64.9278 amu x % abundance of 65Cu% abundance of 65Cu

= 31.4648 amu / 64.9278 amu% abundance of 65Cu = 0.4849

Multiply by 100 to get the percentage.

% abundance of 63Cu = 100% - % abundance of 65Cu% abundance of 63Cu

= 100% - 48.49%% abundance of 63Cu

= 51.51%

Therefore, the percent composition of 63Cu in naturally occurring copper is 51.51%

so you will get moles= 10.0/ 169.87 = 0.05886854654

2. Using stoichiometry you know the equation has 1 mole so the moles of AgCl are gonna be the same; therefore, you will use again the same formula.

3.  moles= mass/molecular mass

0.05886854654 = x/ 143.32
