Problem Details

Consider the equations below. 

(1) Ca (s) + CO2 (g) + 1/2O2 (g) → CaCO3 (s) 

(2) 2Ca (s) + O2 (g) → 2CaO (s) 

How should you manipulate these equations so that they produce the equation below when added: Check all that apply. 

CaO (s) + CO2 (g) → CaCO3 (s) 

(A) reverse the direction of equation (2) 

(B) multiply equation (1) by 3 

(C) multiply equation (2) by 1/2
