Question

Balance the following chemical equation and then answer the questions below. Starting guess for the coefficients of $NH_3$ and $H_2O$ are provided. $\text{\underline{2}}\ NH_3(g) + \text{\underline{}}\ O_2(g) \rightarrow \text{\underline{}}\ NO(g) + \text{\underline{3}}\ H_2O(g)$ a) 8.53 mol of $NH_3(g)$ were reacted with excess $O_2$. How many grams of water vapor were produced? b) 26.7 g of NO(g) were produced in a certain reaction between a limited amount of $O_2$ and excess ammonia. How many moles of $O_2(g)$ were present initially?

Step 1

The given chemical equation is: 2 NH3(g) + O2(g) → 2 NO(g) + 3 H2O(g) To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. Balancing the nitrogen (N) atoms: There are 2 nitrogen atoms Show more…
