Question

BaO+... =Ba(NO3) +... ​

Answer 1

BaO+2HNO3=Ba(NO3)2+H2O

Answer 2

To balance the chemical equation "BaO + ... = Ba(NO3) + ...," we need to determine the missing reactant and product, and then balance the equation.

Given that barium oxide (BaO) reacts to form barium nitrate (Ba(NO3)2), the balanced chemical equation is as follows:

BaO + 2HNO3 → Ba(NO3)2 + H2O

Explanation:

1. BaO is the reactant on the left-hand side. It combines with nitric acid (HNO3) to form barium nitrate (Ba(NO3)2) and water (H2O).

2. To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Balancing the equation:

BaO + 2HNO3 → Ba(NO3)2 + H2O

Now, the equation is balanced:

On the left side:

• 1 Ba atom
• 1 O atom
• 2 H atoms
• 6 O atoms (from 2 HNO3 molecules)

On the right side:

• 1 Ba atom
• 2 N atoms
• 6 O atoms (from 1 Ba(NO3)2 molecule)
• 2 H atoms
• 1 O atom (from H2O)

All the atoms are balanced, and the reaction is complete.
