what equation shows the correct product and obeys conservation of mass for the reaction between potassium and phosphorus?\n$k + p \\rightarrow$\nhint: remember to balance the charges.\n\n$2k + p \\rightarrow k_{2}p$\n$k + p \\rightarrow kp$\n$3k + p \\rightarrow k_{3}p$
Answer
Explanation:
Step1: Identify the charges of the reacting ions
Potassium ($K$) is in Group 1, forming $K^{+}$, and Phosphorus ($P$) is in Group 15, forming $P^{3-}$.
Step2: Determine the neutral chemical formula
To balance charges, three $K^{+}$ ions are needed for one $P^{3-}$ ion, resulting in $K_{3}P$.
Step3: Balance the chemical equation
The reactants must match the product's stoichiometry to obey the conservation of mass. $$3K + P \rightarrow K_{3}P$$
Answer:
$3K + P \rightarrow K_{3}P$
