Question

In a rxn container 100g h2 and 100g cl2 are mixed for the formation of hcl gas. What is the limiting reagent and how much hcl is formed in the rxn?

Answer 1

H2 + Cl2 --------> 2HCl

2g 70g 72g

So, Cl2 is limiting reagent.

70g Cl2------>72g HCl

So, 100g Cl2----->72/70 x 100

=102.75g HCl formed.

Answer 2

Answer:

From a given number of moles of hydrogen and chlorine is 100 g. 100g of chlorine will react with = 270×100=2.86g hydrogen. Option A: this option is wrong because H2 isn't a limiting reagent. Option B: this option is correct because Cl2 is limiting reagent and total mass formed is 104.38g is correct.
