Question

In a lab, we gathered ethyne gas from the reaction betweenCaC2 and H2O (calcium carbide and water) andthen combusted it. These are the balanced chemical equations: CaC2(s) + 2H2O(l) --->Ca(OH)2(s) + C2H2(g) 2C2H2(g) +5O2(g) ---> 4CO2(g) +2H2O(g) Now, I have to theoretically calculate the ratio of air toethyne. I'm supposed to use the balanced equations to calculatethis. Any ideas? (And are the states of the balanced equationright? ex. (g), (s), (l)?)
