Chapter 3, Problem 67GQ

Balance the following equations:

(a) for the synthesis of urea, a common fertilizer

CO₂(g) + NH₃(g) → NH₂CONH₂(s) + H₂O(ℓ)

(b) for the reactions used to make uranium(V1) fluoride for the enrichment of natural uranium

UO₂(s) + HF(aq) → UF₄(s) + H₂O(ℓ) UF₄(s) + F₂(g) → UF₆(s)

(c) for the reaction to make titanium(Ⅵ) chloride, which is then converted to titanium metal

TiO₂(s) + C1₂(g) + C(s) → Ti(s) + CO(g) TiC1₄(ℓ) + Mg(s) → Ti(s) + MgC1₂(s)
