Consider the equations below. (1) ca(s) + co2(g) + 1 2 o2(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) reverse the direction of equation (2) multiply equation (1) by 3 multiply equation (2) by 1/2
