Sodium and water react according to the equation What number of moles of H₂ will be produced when 4.0 mol Na is added to 1.2 mol H₂O?

Question

According to the balanced chemical equation, the ratio of moles of Na to moles of H₂O is 2:1. This means that for every 2 moles of Na, 1 mole of H₂O is consumed. In this case, we have 4.0 mol of Na and 1.2 mol of H₂O. To determine the limiting reactant and the amount of product produced, we need to calculate the amount of H₂O that would be consumed if all of the Na reacted. Using the mole ratio from the balanced equation: 4.0 mol Na × (1 mol H₂O / 2 mol Na) = 2.0 mol H₂O Since we only have 1.2 mol of H₂O, it is the limiting reactant. Therefore, only 0.6 mol of H₂O will be produced when 4.0 mol of Na reacts. So the answer is A) 0.6 mol.
