Write the net chemical equation for the production of acrylic acid from calcium carbide, water and carbon dioxide

To get the net chemical equation, you should write out the two equations and then add the elements or compounds on each side. And then cancel ones that are on each side. 

But first, you'll need to multiply the first equation by 6.

6CaC2(s) + 12H2O(g) + 6C2H2(g) + 3CO2(g) + 4H2O(g) = 6C2H2(g) + 6CaOH2(s) + 5CH2CHCO2H(g) 

6CaC2(s) + 12H2O(g) + 3CO2(g) + 4H2O(g) = 6CaOH2(s) + 5CH2CHCO2H(g) 

6CaC2(s) + 16H2O(g) + 3CO2(g) = 6CaOH2(s) + 5CH2CHCO2H(g) is the net chemical equation.
