Answer 2

Reaction 1: AgNO3 --> Ag + NO2 + O2

The given reaction is a decomposition reaction, where a single compound breaks down into multiple simpler substances. In this case, AgNO3 decomposes to form Ag, NO2, and O2.

The balanced equation for the reaction is:

2 AgNO3 --> 2 Ag + 2 NO2 + O2

Reaction 2: AgF + Na2S --> Ag2S + NaF

The given reaction is a double displacement reaction, also known as a metathesis reaction. In this type of reaction, the cations and anions of two different compounds exchange places to form new compounds.

The balanced equation for the reaction is:

AgF + Na2S --> Ag2S + 2 NaF

Reaction 3: HgO --> Hg + O2

The given reaction is a decomposition reaction, where a single compound breaks down into simpler substances. In this case, HgO decomposes to form Hg and O2.

The balanced equation for the reaction is:

2 HgO --> 2 Hg + O2

Reaction 4: MnO + O2 --> Mn3O4

The given reaction is a combination reaction, where two or more substances combine to form a single compound. In this case, MnO and O2 combine to form Mn3O4.

The balanced equation for the reaction is:

4 MnO + O2 --> 2 Mn3O4

Reaction 5: Cu + O2 --> CuO

The given reaction is a combination reaction, where two or more substances combine to form a single compound. In this case, Cu and O2 combine to form CuO.

The balanced equation for the reaction is:

2 Cu + O2 --> 2 CuO

Please note that the coefficients and types of reactions provided above are based on the given information.
