Question

one molecule of bromine (br₂) and two molecules of potassium chloride (kcl) combine in a reaction. how many atoms are in the products? (1 point)
six
four
three
two

Explanation:

Step1: Write the chemical reaction equation

The reaction is \(Br_2 + 2KCl
ightarrow 2KBr+Cl_2\).

Step2: Calculate the number of atoms in the products

For \(2KBr\): Each \(KBr\) has 2 atoms (\(K\) and \(Br\)), so \(2\times2 = 4\) atoms.
For \(Cl_2\): It has 2 \(Cl\) atoms.
Total atoms: \(4 + 2=6\).

Answer:

six
