Answer 3

The chemical equations you've provided are not balanced. I'll balance them for you:

1. H2O + P4O10 → 4H3PO4 This equation represents the reaction between water (H2O) and tetraphosphorus decaoxide (P4O10) to form phosphoric acid (H3PO4).

2. Ca(NO3)2 → Ca(NO2)2 + O2 This equation represents the decomposition of calcium nitrate (Ca(NO3)2) into calcium nitrite (Ca(NO2)2) and oxygen gas (O2).

3. SO2 + H2O → H2SO3 This equation represents the reaction between sulfur dioxide (SO2) and water (H2O) to form sulfurous acid (H2SO3).

Please note that the provided equations may not necessarily occur under standard conditions, and reaction conditions (such as temperature and pressure) may influence the actual reactions and their products. Balancing chemical equations is an important step in understanding and predicting chemical reactions.
