Question

In a reaction container, 100g of hydrogen and 100 g of `Cl_2` are mixed for the formation of HCl gas. What is the limiting reagent and how much HCl is formed in the reaction ?
A. `H_2` is limiting reagent and 36.5 g of HCl are formed.
B. `Cl_2` is limiting reagent and 102.8 g of HCl are formed.
C. `H_2` is limiting reagent and 142 g of HCl are formed.
D. `Cl_2` is limiting reagent and 73 g of HCl are formed.

Answer 1

`underset(2g)(H_2)+underset(71g)(Cl_2) to underset(73g)(2HCl)`
2g of `H_2` reacts with 71 g of `Cl_2`
100 g of `H_2` reacts with `71/2xx100=3550g " of " Cl_2`
Hence, `Cl_2` is the limiting reagent.
71g of `Cl_2` produces 73 g of HCl
100g of `Cl_2` will produce `73/71xx100=102.8g` of HCl
