How many moles of C2H2 are produced by 3.5 mol CaC2?

CaC2 + 2H2O ==> Ca(OH)2 + C2H2

The equation tells you that you get 1 mol C2H2 for every mole CaC2 reacted.

To determine the number of moles of C2H2 produced from 3.5 mol CaC2, you need to use the balanced chemical equation for the reaction.

The balanced equation for the reaction between CaC2 and H2O to produce C2H2 is:

CaC2 + 2H2O → C2H2 + Ca(OH)2

According to the balanced equation, 1 mol of CaC2 produces 1 mol of C2H2.

Therefore, 3.5 mol of CaC2 will produce an equal number of moles of C2H2.

Hence, 3.5 mol of CaC2 will produce 3.5 mol of C2H2.

To determine the number of moles of C2H2 produced by 3.5 mol CaC2, we need to use the balanced chemical equation for the reaction that produces C2H2.

The balanced equation is:
CaC2 + 2H2O → C2H2 + Ca(OH)2

From the balanced equation, we can see that 1 mol of CaC2 produces 1 mol of C2H2.

Therefore, if we have 3.5 mol of CaC2, we will produce 3.5 mol of C2H2.
