Question

H2 + CaCl2 --> 2HCl + Ca How many grams of HCl are made when 2.93 g of

Ca are made?

Answer 1

H2 + CaCl2 -> 2HCl + Ca

How many grams of HCl are made when 2.93 g of

Ca are made?

Step-by-step explanation:

From the given balanced chemical equation, it is clear that:

2mol. of HCl and 1mol. of Ca are produced.

2mol. of HCl weighs --- 73.0g

1mol. of Ca weighs --- 40.0g

Hence,

73.0g of HCl and 40.0g of Ca are produced.

When 2.93g of Ca is produced then, how many grams of HCl will be produced?

`=> 2.93g Ca * (73.0g HCl)/(40.0g Ca) \\=5.35g HCl`

Hence, 5.35g of HCl is formed.
