Question 3 • Chemistry

Which statement best describes the formula equation Cl sub 2 times g plus 2 KBr aq ce bond right arrow 2 KCl aq plus Br sub 2 times l ?

Answer
A
Potassium bromine gas reacts with liquid chlorine to form potassium chloride in solution and bromine gas.
B
Bromine gas reacts with a solution of potassium chloride to form potassium bromide and chlorine gas.
C
Chlorine gas reacts with potassium bromide to form potassium chloride in solution and liquid bromine.
D
Carbon iodide reacts with potassium bromide to form potassium carbon iodide and bromine.

Explanation

Read the reactants on the left side of the equation: Cl₂(g) is chlorine gas, and KBr(aq) is potassium bromide dissolved in water. The products on the right are KCl(aq), potassium chloride in solution, and Br₂(l), liquid bromine. Therefore, choice C correctly describes the reaction.
