Question

How many grams of cl are required to completely react with 0.40 g of hydrogen and also calculate the amount of hcl formed?

Answer 1

The formation of HCl can be represented as follows:
              H2 + Cl2 → 2HCl
​Here, 1 mole of H2 reacts with 1 mole of Cl2 to give 2 moles of HCl.
Given,
    0.4 g H2 is present,
       Number of moles of H2 = 0.4/2 = 0.2
As 1 mole of H2 gives 2 moles of HCl,
     0.2 moles of H2 will give 2 x 0.2 = 0.4 moles of HCl
​       Hence, grams of HCl = 0.2 x 36.5 = 7.3 g of HCl
As 2 moles of HCl is formed by 1 mole of Cl2,
      0.4 moles of HCl corresponds to 0.2 moles of Cl​2 
Therefore,
      Grams of Cl2 = 0.2 x (35.5 x 2) = 0.2 x 71 = 14.2 g of Cl2
