Question

Determine the mass of calcium hydroxide produced when calcium carbide (CaC2) reacts with 0.64 grams of water according to the following balanced chemical equation:
CaC2 + 2H2O -> Ni(OH)2 + NaNO3

Answer 1

Here is a worked example. Just follow the steps.

Answer 2

That's about temperature, mine's not. I kind of know the steps but im not getting the right answer, which is 1.32 g Ca(OH)2

Answer 3

Hallie, there is nothing in that post about temperature. It is about how to calculate grams oxygen produced by KClO3 and it gives you a step by step procedure for solving stoichiometry problems. You might have more luck if you had the right equation. I can tell you that
CaC2 + 2H2O does not give you Ni(OH)2 + NaNO3

Answer 4

Also, I don't believe 1.32 g Ca(OH)2 is the correct answer.
