Question

5 grams of H2 react with 29 grams of Oz to yield water

a) Which is the limiting reagent?

b) Calculate the maximum amount of water that can be formed?​

Answer 1

Answer:

A. Limiting agent is the molecule or compound which is in less amount for continuation of the reaction.

B. 5g H2 means 2.5 mole of H2.

29 g O2 means 1.81 mole.

2 moles of H2 and 1 mole of O2 will give 2 moles of H2O thus, 36 g of H2O is formed.

Answer 2

Answer:

But according to the question, 29 g of O₂ is present. So, the limiting reactant is hydrogen. 1 g of H₂ forms 36/4 g of H₂O. Maximum amount of water that can be formed is 27 g
