Answer 1

1) 2H2O2 = 2H2O + O2
2) 2KMnO4 = K2MnO4 + MnO2 + O2
3) 2HgO = 2Hg + O2
4) 2NaNO3 = 2NaNO2 + O2

Answer 2

1) 2H₂O₂ → 2H₂O+O₂
2) 2KMnO₄→ K₂MnO₄ +MnO₂+ O₂
3) 2HgO→ 2Hg +O₂
4) 2NaNO₃ → 2NaNO₂ +O₂

Answer 3

Conversion of Reaction Schemes to Equations

Here are the equations corresponding to the given reaction schemes:

1) H2O2 → H2O + O2 2) KMnO4 → K2MnO4 + MnO2 + O2 3) HgO → Hg + O2 4) 2NaNO3 → 2NaNO2 + O2

Please note that the numbers in front of the chemical formulas represent the stoichiometric coefficients, which indicate the relative amounts of each substance involved in the reaction.

Let's break down each reaction and explain the conversion process.

1) H2O2 → H2O + O2 This equation represents the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2).

2) KMnO4 → K2MnO4 + MnO2 + O2 This equation represents the reaction of potassium permanganate (KMnO4) to form potassium manganate (K2MnO4), manganese dioxide (MnO2), and oxygen gas (O2).
