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
