Answer 3

To balance the chemical equation MgO + HNO3 → Mg(NO3)2, we need to make sure that the number of atoms of each element is the same on both sides of the equation. Here's how you can balance it:

MgO + 2HNO3 → Mg(NO3)2 + H2O

Balancing the equation involves adjusting the coefficients in front of each compound to ensure that the number of each type of atom is the same on both sides of the equation. In this case, we added a coefficient of 2 in front of HNO3 on the left side to balance the nitrogen (N) and oxygen (O) atoms. We also added a coefficient of 2 in front of H2O on the right side to balance the hydrogen (H) and oxygen (O) atoms.

Now the equation is balanced with the same number of atoms on both sides:

1 Mg atom on both sides 2 N atoms on both sides 6 O atoms on both sides 2 H atoms on both sides
