2 barium atoms, 1 silver atom, and 4 oxygen atoms
2 barium atoms, 1 silver atom, and 4 oxygen atoms

2 gallium atoms, 1 silicon atom, and 4 oxygen atoms

Answer 1

The chemical formula K2SO4 consists of the following elements:

• K represents potassium.
• S represents sulfur.
• O represents oxygen.

In the formula K2SO4:

• The "2" before K indicates there are 2 potassium atoms.
• There is no subscript for sulfur, indicating there is 1 sulfur atom.
• The "4" before O indicates there are 4 oxygen atoms.

So, the breakdown is as follows:

• 2 potassium atoms (K)
• 1 sulfur atom (S)
• 4 oxygen atoms (O)

The correct response is:

2 potassium atoms, 1 sulfur atom, and 4 oxygen atoms.
