The reaction is:
NH4 (NO3) (s) ⇄ N2O (g) + 2 H2O (g)
This means that 1 mol of NH4 (NO3)s produces 3 moles of gases.
Now find the number of moles in 1.71 kg of NH4 (NO3)
Molar mass = 2*14g/mol + 4 * 1g/mol + 3*16g/mol = 80 g/mol
# moles = mass / molar mass = 1710 g / 80 g/mol = 21.375 mol of NH4(NO3)
We already said that every mol of NH4(NO3) produces 3 moles of gases, then the number of moles of gases produced is 3 * 21.375 = 64.125 mol
Now use the equation for ideal gases to fin the volume
pV = nRT => V = nRT / p = (64.125 mol)(0.082atm*liter / K*mol) * (119 +273)K / (731mmHg *1 atm/760mmHg) =
V = 2143.01 liters
Answer:
Carbon comes from the air and soil, hydrogen comes from absorbing water, H20, and breaking it down into Hydrogen and oxygen :) (also where oxygen comes from)

Answer:
132.94 kilo joules
Explanation:
We are given;
- Mass of benzene solution is 850 g
- Temperature change from 95°C to 3° C = 92° C or 92 K
We are required to determine the energy released by the cooling of benzene.
Taking the specific heat capacity of liquid benzene as 1.7 kJ/kg/K
Then we can determine the amount of heat energy released by using the formula;
Heat = Mass × specific heat × change in temperature
= 0.85 kg × 1.7 kJ/kg/K × 92 K
= 132.94 kilo joules
Therefore, the heat released by cooling benzene is 132.94 kilo joules
