Answer 1

Answer:

A synthesis reaction or direct combination reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. The reactants may be elements or compounds, while the product is always a compound.

Water:

2 H2(g) + O2(g) → 2 H2O(g)

Carbon dioxide:

2 CO(g) + O2(g) → 2CO2(g)

Ammonia:

3 H2(g) + N2(g) → 2 NH3(g)

Aluminum oxide:

4 Al(s) + 3 O2(g) → 2 Al2O3(s)

Iron sulfide:

8 Fe + S8 → 8 FeS

Potassium chloride:

2 K(s) + Cl2(g) → 2 KCl(s)
