2HCl + Ca(OH)2 --> CaCl2 + 2H2O That means you need twice as many moles of HCl as you have of the Ca(OH)2 I'll let you do the math.

Balanced equation.

2HNO3 + Ca(OH)2 -> Ca(NO3)2 + 2H2O

1 mole Ca(OH)2 (2 mole HNO3/1 mole Ca(OH)2)

= 2 moles nitric acid should do it.

Balanced equation first.

CaCO3 + 2HCl -> CaCl2 + CO2 + H2O

2.5 moles CaCO3 (2 mole HCl/1 mole CaCO3)

= 5.0 moles HCl required
