Question

Na2О2 + КМпО4 + H2SO4 →

Answer 1

5Na2O2 + 2KMnO4 + 8H2SO4 → 5O2 + 2MnSO4 + 5Na2SO4 + K2SO4 + 8H2O

Answer 2

To balance the chemical equation, we need to determine the coefficients that will ensure the same number of atoms for each element on both sides of the equation. Let's balance the given chemical equation step by step:

Na2O2 + KMnO4 + H2SO4 →

Step 1: Balance the potassium (K) atoms: There is one potassium atom on the left side (KMnO4) and none on the right side. To balance the potassium atoms, add a coefficient of 1 in front of K2MnO4.

Na2O2 + K2MnO4 + H2SO4 →

Step 2: Balance the manganese (Mn) atoms: There is one manganese atom on the left side (KMnO4) and one on the right side (K2MnO4). The manganese atoms are already balanced.

Na2O2 + K2MnO4 + H2SO4 →

Step 3: Balance the sodium (Na) atoms: There are two sodium atoms on the left side (Na2O2) and none on the right side. To balance the sodium atoms, add a coefficient of 2 in front of Na2O2.

2 Na2O2 + K2MnO4 + H2SO4 →

Step 4: Balance the oxygen (O) atoms: There are four oxygen atoms on the left side (2 Na2O2) and ten on the right side (K2MnO4 + H2SO4). To balance the oxygen atoms, add a coefficient of 5 in front of H2SO4.

2 Na2O2 + K2MnO4 + 5 H2SO4 →

Now the chemical equation is balanced, and the final balanced equation is:

2 Na2O2 + K2MnO4 + 5 H2SO4 → (products)
