• Sodium chloride and potassium nitrate

• Calcium carbonate and sulfuric acid

• Magnesium oxide and hydrochloric acid

How many chlorine atoms are initially present in the equation?

• One

• Two

• Three

• Four

What is the significance of the sulfate ion in the balancing process?

• It is ignored during balancing.

• It is replaced with a different ion.

• It is counted as a single unit to simplify balancing.

• It is split into sulfur and oxygen for balancing.

What is the chemical formula for the sulfate ion?

• SO3

• SO4

• SO2

• S2O4

What adjustment is made to balance the chlorines and potassiums in the equation?

• Remove sulfate ions
