When cac2 reacts with water, what carbon-containing compound forms? when reacts with water, what carbon-containing compound forms? c2h2 ch4 co h2co3 co2?

Notice that each reactant is made up of two elements. To predict the products, all you have to do is interchange the combination of the two reactants while taking note that metal comes first, followed by nonmetals. With that being said, the reaction would be:

CaC₂ + 2 H₂O --> C₂H₂ + Ca(OH)₂ 

So, the answer is C₂H₂.

The answer for this question is d. none of these
