Ca(OH)₂ + HCl ---> CaCl₂ + H₂O

Question

What is the mole relation of this balanced equation?

Answer 1

well, I suppose you better balance it
x Ca(OH)₂ + y HCl ---> ? CaCl₂ +? H₂O for starters
x Ca(OH)₂ + y HCl ---> x CaCl₂ + ? H₂O for Ca balance
x Ca(OH)₂ + 2x HCl --> x CaCl₂ + z H₂O y = 2x for Cl balance
what about z? , balance H
2 x + 2x = 2z so z = 2x
x Ca(OH)₂ + 2x HCl --> x CaCl₂ +2x H₂O
so try
1 Ca(OH)₂ + 2 HCl --> 1 CaCl₂ +2 H₂O Whew O came out 2 on each side
2 mols HCl for every mol Ca(OH)₂ etc
