Answer 3

To balance the chemical equation ZnO + HNO3 = Zn(NO3)2, you need to ensure that the same number of each type of atom is present on both sides of the equation. Here's how to balance it:

ZnO + HNO3 = Zn(NO3)2

1. Start with the atoms that appear in only one compound on each side: Zn: 1 Zn on the left, 1 Zn on the right H: 1 H on the right, none on the left N: 1 N on the right, 2 N on the left O: 3 O on the right (from HNO3 and Zn(NO3)2), 1 O on the left (from ZnO)

2. Balance the atoms by adding coefficients to each compound as needed: ZnO + HNO3 = Zn(NO3)2 ZnO + 2HNO3 = Zn(NO3)2

Now, the balanced equation is:

ZnO + 2HNO3 = Zn(NO3)2

The coefficients are: ZnO: 1 HNO3: 2 Zn(NO3)2: 1

The sum of the coefficients is 1 + 2 + 1 = 4.
