Question

Question:Complete and balance each of the following chemical equations. (In some cases, there may be more than one correct answer.)

(a) \({{\rm{P}}_4} + {\rm{Al}}\)

(b) \({{\rm{P}}_4} + {\rm{Na}}\)

(c) \({{\rm{P}}_4} + {{\rm{F}}_2}\)

(d) \({{\rm{P}}_4} + {\rm{C}}{{\rm{l}}_2}\)

(e) \({{\rm{P}}_4} + {{\rm{O}}_2}\)

(f) \({{\rm{P}}_4}{{\rm{O}}_6} + {{\rm{O}}_2}\)

Short answer

The balanced chemical equations are:

\(\begin{array}{l}a){P_4}+4Al \to 4{\rm{AlP}}\\b){P_4}+12{\rm{Na}}\to 4{\rm{N}}{{\rm{a}}_3}{\rm{P}}\\c){P_4}+6{F_2}\to 4P{F_3}{P_4}+10{F_2}\to 4P{F_5}{P_4}+4{F_2} \to 2{P_2}{F_4}\\d){P_4}+6{\rm{C}}{{\rm{l}}_2} \to 4{\rm{PC}}{{\rm{l}}_3}{{\rm{P}}_4}+10{\rm{C}}{{\rm{l}}_2}\to4{\rm{PC}}{{\rm{l}}_5}\\e){P_4}+3{{\rm{O}}_2} \to {{\rm{P}}_4}{{\rm{O}}_6}\\f){P_4}{O_6}+2{O_2} \to {P_4}{O_1}_0\end{array}\)

Step-by-step solution

Definition of chemical equation.

A chemical equation is a symbolic representation of a chemical reaction in the form of symbols and formulae, with the reactant entities on the left and the product entities on the right, with a plus sign between the entities in both the reactants and the products, and an arrow pointing towards the products, indicating the reaction's direction.

Write the chemical equations.

The chemical equations are

\(\begin{array}{l}a){P_4}+4Al\to4{\rm{AlP}}\\b){P_4}+12{\rm{Na}} \to 4{\rm{N}}{{\rm{a}}_3}{\rm{P}}\\c){P_4} + 6{F_2} \to 4P{F_3}{P_4}+10{F_2} \to 4P{F_5}{P_4}+4{F_2}\to 2{P_2}{F_4}\\d){P_4}+6{\rm{C}}{{\rm{l}}_2} \to 4{\rm{PC}}{{\rm{l}}_3}{{\rm{P}}_4}+10{\rm{C}}{{\rm{l}}_2} \to 4{\rm{PC}}{{\rm{l}}_5}\\e){P_4}+3{{\rm{O}}_2}\to{{\rm{P}}_4}{{\rm{O}}_6}\\f){P_4}{O_6}+2{O_2} \to {P_4}{O_1}0\end{array}\)
