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

a four
b three
c two
d six

Answer 1

The equation for the reaction is:

Br2 + 2KCl -> 2KBr + Cl2

In the products, there are 2 potassium bromide (KBr) molecules, which contain 2 potassium (K) atoms. Additionally, there is 1 molecule of chlorine gas (Cl2), which contains 2 chlorine (Cl) atoms.

Therefore, the total number of atoms in the products is 2 potassium (K) atoms + 2 chlorine (Cl) atoms = 4 atoms.

Answer: a) four
