Answer to Question #142022 in General Chemistry for Prin

Question

What mass of calcium chloride will be produced from 4.09g of HCl reacting with Ca(OH)2

Answer 1

Ca(OH)₂ + 2HCl = CaCl₂ + 2H₂O

2HCl will give CaCl₂

2×(1+35.5)g of HCl will give 40+(2×35.5)g of CaCl₂

73g of HCl will give 111g of CaCl₂

1g of HCl will give 111/73 g of CaCl₂

4.09g of HCl will give (111/73)×4.09g of CaCl₂

4.09g of HCl will give 6.219g of CaCl₂
