Balance the following equations:(a) for the synthesis of urea, a common fertilizerCO2(g) + NH3(g) → NH2CONH2(s) + H2O(ℓ)(b) for the reactions used to make uranium(V1) fluoride for the enrichment of natural uraniumUO2(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 metalTiO2(s) + C12(g) + C(s) → Ti(s) + CO(g) TiC14(ℓ) + Mg(s) → Ti(s) + MgC12(s)

(a)

Interpretation Introduction

Interpretation:

The balanced equation for the sulfur trioxide in water should be given.

Concept introduction:

The law of conservation of mass states that no atoms can be created or destroyed in a chemical reaction, therefore, the number of atoms present in the reactants is equal to the number of atoms present in the products.

Explanation

Carbon dioxide is reacts with water molecule which forms urea and water, the balanced equation for the formation of urea is given above.

Balance the equation,

Balance the hydrogen atom in the given equation, when balancing the equation, we should not alter the subscripts and we can change coefficients...
