the balanced equation for the reaction is

N₂ + 3H₂ --> 2NH₃

since number of moles of gas is directly proportional to volume of gas once all other parameters are kept constant

the volume ratio of reactant gases is equal to molar ratio

therefore volume ratio of H₂ to NH₃ is 3:2

so 3 L of H₂ reacts to produce 2 L of NH₃ assuming N₂ is in excess

when 3.6 L of H₂ reacts - 2/3 x 3.6 L = 2.4 L of N₂ is formed

So 2.4 L of NH₃ is produced

Answer:

2.4 L is the correct answer

Explanation:

volume ratio= 2NH3/3H2

3.6*2/3=2.4 L

I this isn't clear enough the other person has a really good explanation.

6) A 14.5 g sample of sodium chloride reacts with excess fluorine gas according to

Ann [662]

The mass of chlorine gas produced by 14.5 grams of sodium chloride is 10.42 g.

The mass of chlorine gas produced by 14.5 grams of sodium chloride is 8.81 g.

The given parameters;

mass of the sodium chloride, = 14.5 g
2NaCl(s) + F2(g) → 2NaF(s) + Cl2(g)

In the reaction above, we can deduce the following;

molecular mass of 2Nacl = 2(58.44) = 116.88 g

molecular mass of 2NaF = 2(42) = 84 g

molecular mass of Cl2 = 71 g

The mass of sodium fluoride produced by 14.5 grams of sodium chloride is calculated as follows;

116.88 g of NaCl --------------- 84 g of NaF

14.5 g of NaCl ------------------- ?

$= \frac{84 \times 14.5}{116.88} \\\\= 10.42 \ g$

The mass of chlorine gas produced by 14.5 grams of sodium chloride is calculated as follows;

116.88 g of NaCl --------------- 71 g of Cl2

14.5 g of NaCl ------------------- ?

$= \frac{14.5 \times 71}{116.88} \\\\= 8.81 \ g$

Calculate the value deltaG°

atroni [7]

Answer:

ΔG=ΔG0+RTlnQ where Q is the ratio of concentrations (or activities) of the products divided by the reactants. Under standard conditions Q=1 and ΔG=ΔG0 . Under equilibrium conditions, Q=K and ΔG=0 so ΔG0=−RTlnK . Then calculate the ΔH and ΔS for the reaction and the rest of the procedure is unchanged.
