)BaSO4

1 answer

To balance the given chemical equation:

\[ \text{BaO}_2 + \text{H}_2\text{SO}_4 \rightarrow \text{H}_2\text{O}_2 + \text{BaSO}_4 \]

  1. Count the number of atoms for each element on both sides of the equation:

    • Reactants:
      • Ba: 1 (from BaO2)
      • O: 2 (from BaO2) + 4 (from H2SO4) = 6
      • H: 2 (from H2SO4)
      • S: 1 (from H2SO4)
    • Products:
      • H: 2 (from H2O2)
      • O: 2 (from H2O2) + 4 (from BaSO4) = 6
      • Ba: 1 (from BaSO4)
      • S: 1 (from BaSO4)

  2. Balance the equation:

    • Both sides have the same number of Ba (1), S (1), and O (6) atoms as well as H (2).

It appears that all elements are already balanced. Thus, the coefficients that balance the chemical equation are:

(1) BaO2 + (1) H2SO4 → (1) H2O2 + (1) BaSO4

So the balanced equation is:

\[ 1 \text{BaO}_2 + 1 \text{H}_2\text{SO}_4 \rightarrow 1 \text{H}_2\text{O}_2 + 1 \text{BaSO}_4 \]

Coefficients: (1), (1), (1), (1).
