10. Carbon tetrachloride may be prepared by the reaction of natural gas (methane CH4) and elemental chlorine gas in the presence of ultraviolet light. Write the UNBALANCED chemical equation for this process.
A. CH4 (g) + Cl2 (g) --------> C(Cl)4
11. Calcium oxide reacts with moisture in the air and is converted to calcium hydroxide. Write the UNBALANCED chemical equation for this process.
A. CaO (aq) + H2O (l) --------> CaOH
12. Ammonium nitrate breaks down into nitrogen gas, oxygen gas, and water vapor. Write the UNBALANCED chemical equation for this process.
A. NH4NO3 (aq) --------> N2 (g) +O2 (g) + H2O (g)

.....................................u.v.
10. CH4 (g) + Cl2 (g) ---------> CCl4 + HCl
You should state that ultraviolet (uv) light drives the reaction.
The brackets around Cl are not required.
11. CaO (aq) + H2O (l) --------> Ca(OH)2
12. is fine.

10] CH4 (g) + Cl2 (g) ----uv----> C(Cl)4 + HCl
11] CaO (SOLID) + H2O (GAS or vapor) --------> Ca(OH)2
12] looks OK to me
