🤓 Based on our data, we think this question is relevant for Professor Bindell's class at UCF.

Solution: When 35.6 L of ammonia and 40.5 L of oxygen gas at STP burn, nitrogen monoxide and water form. After the products return to STP, how many grams of nitrogen monoxide are present?          NH 3(g) + O2(g) ⟶NO(g) + H2O(l)     [unbalanced]

Problem

When 35.6 L of ammonia and 40.5 L of oxygen gas at STP burn, nitrogen monoxide and water form. After the products return to STP, how many grams of nitrogen monoxide are present?

          NH 3(g) + O2(g) ⟶NO(g) + H2O(l)     [unbalanced]

Solution

In order to find the mass of the NO, we need to find the limiting reactant of this reaction.

But first we need to balance the given reaction:
