5. The combustion of coal with oxygen forms CO2 and releases 94 kcal of energy. C(s) + O2(g) → CO2(g) ΔH = -94 kcal/mol

a. How much energy is released when 2.5 mol of C reacts?
b. How much energy is released when 3.0 mol of O2 reacts?
c. How much energy is released when 25.0 g of C reacts?

How is the solubility of a carbon dioxide gas in water increase?

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
