Answer :
Final answer:
From the balanced chemical reaction, we can see that the molar ratio of oxygen to water is 1:2. Hence, 1.57 moles of oxygen would produce 3.14 moles of water in the reaction.
Explanation:
The subject of this question is stoichiometry in chemistry which involves understanding chemical equations and using them to solve problems like calculating the quantity of a product or reactant. In the given balanced chemical equation 2H₂(g) + O₂(g) → 2H₂O(g), we can notice that 1 mole of O₂ reacts with 2 moles of H₂ to produce 2 moles of H₂O. This means that the molar relationship between O₂ and H₂O is 1:2. So, if we have 1.57 moles of O₂ reacting, we will get a two-fold amount which is 3.14 moles of H₂O as the product.
