How many mols of CaC2 are needed to react completely with 60.2 mols of H2O? CaC2 + 2H2O → C2H2 + Ca(OH)2

30.1 moles of CaC₂  are needed.

Explanation:

Given data:

Number of moles of CaC₂ needed = ?

Number of moles of H₂O = 60.2 mol

Solution:

Chemical equation;

CaC₂ + 2H₂O      →    C₂H₂ + Ca(OH)₂

Now we will compare the moles of CaC₂ and H₂O.

                           H₂O       :       CaC₂        

                             2          :          1

                           60.2      :        1/2×60.2 = 30.1 mol

30.1 moles of CaC₂  are needed.

the answer is true. hope it .
