Question

Using the balanced equation CaC₂(ş) + 2 H₂O(1) --> C₂H₂(g) + Ca(OH)₂(aq) how many moles of Ca(OH)2 would be produced if 3.5 moles of H₂O are consumed?​

Answer 1

1.75 moles

Step-by-step explanation:

According to CaC₂(s) + 2 H₂O(l) --> C₂H₂(g) + Ca(OH)₂(aq)

2 moles of H20 will produce 1 mole of Ca(OH)2

therefore 3.5 moles of H2O will produce 3.5 x (1/2) = 1.75 moles of Ca(OH)2
