Типы реакций

1) HgO = ?

The reaction you provided, HgO = ?, is incomplete. It is missing the reactants or products. Please provide the complete equation so that I can help you further.

2) Ae + HCE = ?

The reaction you provided, Ae + HCE = ?, is also incomplete. It is missing the reactants or products. Please provide the complete equation so that I can assist you better.

3) N2 + O2 = ?

The reaction you provided, N2 + O2 = ?, represents the combination of nitrogen gas (N2) and oxygen gas (O2). This is a synthesis reaction, also known as a combination reaction, where two or more substances combine to form a single compound. In this case, nitrogen gas and oxygen gas combine to form nitrogen dioxide (NO2) according to the balanced equation:

N2 + O2 → 2NO2 4) Fe2O3 + C = ?

The reaction you provided, Fe2O3 + C = ?, represents the combination of iron(III) oxide (Fe2O3) and carbon (C). This is a redox reaction, specifically a reduction reaction, where iron(III) oxide is reduced to iron metal. The balanced equation for this reaction is:

Fe2O3 + 3C → 2Fe + 3CO 5) Ca + Si = ?

The reaction you provided, Ca + Si = ?, represents the combination of calcium (Ca) and silicon (Si). This is a synthesis reaction, where two elements combine to form a compound. However, calcium and silicon do not readily react with each other under normal conditions. Therefore, this reaction is not commonly observed.

6) MgO = ?

The reaction you provided, MgO = ?, represents the decomposition of magnesium oxide (MgO). This is a thermal decomposition reaction, where a compound breaks down into its constituent elements or simpler compounds upon heating. The balanced equation for this reaction is:

2MgO → 2Mg + O2 7) H + Br + HL(OH)3 = ?

The reaction you provided, H + Br + HL(OH)3 = ?, is incomplete and unclear. It seems to be missing the reactants or products. Please provide the complete equation so that I can assist you better.
