Enter your answer in the provided box. Calculate AHan for
Ca(s) + 1/2 O2(g) + CO2(g) → CaCO3(s)
given the following set of reactions:
Ca(s) + 1/2 0g) – CaOs)
CaCO3(s) + Ca(s) + CO2(g)
AH= -635.1 kJ
AH=178.3 kJ
kJ

Calcium hydride (cah2) reacts with water to form hydrogen gas: cah2(s) + 2h2o(l) → ca(oh)2(aq) + 2h2(g) how many grams of cah2 are needed to generate 45.0 l of h2 gas at a pressure of 0.995 atm and a temperature of 32 °c?
