Question

Find out the amount of hcl formed from 5g h2 and 20g cl2

Answer 1

So if 0.200 mol acid react, then (by the stoichiometry), 1/2 this quantity, i.e. 0.100 mol of dihydrogen.

The limiting reactant is HCl , which will produce 0.202 g H2 under the stated conditions.

It should determine Moles of 2M Hydrochloric Acid, and then multiply times the molar mass of hydrogen gas, 2.01588 g/mol.

Answer 2

$\huge \tt0.200 \: \: mol$
