Final answer:
To balance the reaction between HNO3(aq) and Ba(OH)2(aq), the equation is 2 HNO3(aq) + Ba(OH)2(aq) → 2 H2O(l) + Ba(NO3)2(aq), with two HNO3 molecules and one Ba(OH)2 molecule producing two molecules of water and one molecule of barium nitrate.
Step-by-step explanation:
To complete the balanced neutralization equation for the reaction between HNO3(aq) and Ba(OH)2(aq), we start with the unbalanced chemical equation:
HNO3(aq) + Ba(OH)₂ (aq) → H₂O(l) + Ba(NO3)₂ (aq)
Since the base Ba(OH)₂ has two hydroxide ions, we will need two molecules of HNO3 to neutralize it fully and produce two molecules of water. Therefore, the balanced equation will be:
2 HNO3(aq) + Ba(OH)₂ (aq) → 2 H₂O(l) + Ba(NO3)₂(aq)
