Step-by-step explanation:
According to the problem, hydrochloric acid will react with oxygen gas to produce water and chlorine gas.
hydrochloric acid + oxygen gas ----> water + chlorine gas
The balanced equation will be:
4 HCl + O₂ -----> 2 H₂O + 2 Cl₂
If we pay attention to the coefficients of the reaction we will see that 4 moles of HCl will react with 1 mol of O₂ to produce 2 moles of H₂O and 2 moles of Cl₂. So, 1 mol of O₂ will produce 2 moles of H₂O. The molar ratio between O₂ and H₂O is 1 to 2.
1 mol of O₂ : 2 moles of H₂O molar ratio
We can use this relationship to find the number of moles of H₂O that are produced from 5.52 moles of O₂.
moles of H₂O = 5.52 moles of O₂ * 2 moles of H₂O/(1 mol of O₂)
moles of H₂O = 11.0 moles
Answer: 11.0 moles of water are produced from 5.52 moles of oxygen gas.
