Answer 1

Ответ:

Объяснение:

2HNO3 + CaO -> Ca(NO3)2 + H2O

4Fe + 3O2 -> 2Fe2O3

BaO + H2SO4 -> BaSO4 + H2O

2Fe + 3Cl2 -> 2FeCl3

Answer 2

It appears that you have provided a list of chemical reactions and equations, and you are asking for their solutions. However, there seem to be some errors in the way the reactions are written. Let me correct them and provide the balanced chemical equations for each reaction:

1. HNO3 + CaO → Ca(NO3)2 + H2O Nitric acid (HNO3) reacts with calcium oxide (CaO) to form calcium nitrate (Ca(NO3)2) and water (H2O).

2. 4Fe + 3O2 → 2Fe2O3 Iron (Fe) reacts with oxygen gas (O2) to form iron(III) oxide (Fe2O3), commonly known as rust.

3. BaO + H2SO4 → BaSO4 + H2O Barium oxide (BaO) reacts with sulfuric acid (H2SO4) to form barium sulfate (BaSO4) and water (H2O).

4. 2Fe + 3Cl2 → 2FeCl3 Iron (Fe) reacts with chlorine gas (Cl2) to form iron(III) chloride (FeCl3).

Please note that these balanced chemical equations represent the correct reactions based on the provided reactants and products. If you have any other questions or need further explanations, feel free to ask!
