In which of the following reactions do five total molecules of reactants produce four total molecules of products? (points : 3) n2 + 3h2 2nh3 sno2 + 2h2 sn + 2h2o 2h2s + 3o2 2so2 + 2h2o 2so2 + o2 2so3

The correct answer is

Explanation:

We are asked a reaction in which five molecules of reactants produce 4 molecules of products.

From the given options:

Here, 1 mole of nitrogen is reacting with 3 moles of hydrogen to produce 2 moles of ammonia. In other words, 4 molecules of reactants produce 2 molecules of product.

Here, 1 mole of tin oxide reacts with 2 moles of hydrogen to produce 1 mole of tin and 2 moles of water. In other words, 3 molecules of reactants produce 3 molecules of product.

Here, 2 moles of hydrogen sulfide reacts with 3 moles of oxygen to produce 2 moles of sulfur dioxide and 2 moles of water. In other words, 5 molecules of reactants produce 4 molecules of product.

Here, 2 moles of sulfur dioxide reacts with 1 mole of oxygen to produce 2 moles of sulfur trioxide. In other words, 3 molecules of reactants produce 2 molecules of product.

Hence, the correct answer is option 3.
