One molecule of bromine (Br) and two molecules of potassium chloride (KCI) combine in a reaction. How many atoms are in the products? (1 point)

Question

O six
O four
O three
O two

Answer 1

The reaction equation is:

Br + 2KCl -> 2KBr + Cl2

In this reaction, one molecule of bromine (Br) combines with two molecules of potassium chloride (KCl) to produce two molecules of potassium bromide (KBr) and one molecule of chlorine (Cl2).

Since each molecule of KBr contains one bromine atom and each molecule of Cl2 contains two chlorine atoms, the total number of atoms in the products is:

1 bromine atom (from KBr) + 2 chlorine atoms (from Cl2) = 3 atoms

Therefore, the correct answer is three (O three).
