Fe+s= Fes

C+O2= CO2

Answer 2

Reactions and Balanced Equations:

Here are the reactions and their balanced equations:

1. 2NH3 = N2 + 3H2 - This is the reaction of ammonia (NH3) decomposing into nitrogen gas (N2) and hydrogen gas (H2) [[1]].

2. 2HgO = 2Hg + O2 - This is the reaction of mercury(II) oxide (HgO) decomposing into mercury (Hg) and oxygen gas (O2) [[2]].

3. Fe + S = FeS - This is the reaction of iron (Fe) reacting with sulfur (S) to form iron(II) sulfide (FeS) [[3]].

4. C + O2 = CO2 - This is the reaction of carbon (C) reacting with oxygen gas (O2) to form carbon dioxide (CO2) [[4]].

Please note that these reactions are balanced equations, which means that the number of atoms on both sides of the equation is equal.

I hope this helps! Let me know if you have any further questions.
