How many moles of CaCl2 will be produced from 1.4 moles of HCl reacting with calcium hydroxide?

0.7 mol of CaCl2 is produced.

Explanation:

First, you have to create a balanced equation:

Ca (OH) 2 + 2HCl - > CaCl2 + 2H2O

Next, we have to find the ratio using the coefficients of the equation:

1Ca (OH) 2 + 2HCl - > 1CaCl2 + 2H20

Ratio,

1 : 2 : 1 : 2

By looking at the ratio, we know that 2 ratio of HCl react to produce 1 ratio of CaCl2. Now, we can find the mole of CaCl2:

ratio of 2 = 1.4 mol

ratio of 1 = 0.7 mol
