Please help ASAP, please explain the answer. None of this makes sense. 27. "Smelling salts," which are used to revive someone who has fainted, typically contain ammonium carbonate, (NH4)2,CO3. Ammonium carbonate decomposes readily to form ammonia, carbon dioxide, and water. The strong odor of the ammonia usually restores consciousness in the person who has fainted. The unbalanced equation is (NH4)2CO3(s) ---> NH3(g) + CO2,(g) + H2O(g)

Calculate the mass of ammonia gas that is produced if 1.25 g of ammonium carbonate decomposes completely.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
