Sulfur dioxide reacts with water. Upon predicting the product and balancing the equation, which of the following can be found on the product side?

• H2SO3

• H2SO4

Answer explanation

Sulfur is nonmetal. Nonmetal oxides form acids when they react with water. The reaction between sulfur dioxide and water is:

SO2+H2O→H2SO3

The reaction is already balanced, and no coefficient is needed.

Using your reference sheet, identify the type of synthesis reaction:

K₂O + H₂O -->

• Metal + nonmetal

• Metal oxide + water reaction

• Nonmetal + oxygen reaction

• Nonmetal oxide + water reaction

Using your reference sheet, identify the type of synthesis reaction:

Mg + I₂ -->

• Metal + Nonmetal

• Metal oxide + water reaction

• Nonmetal + oxygen

• Nonmetallic oxide + water

What is the product of the synthesis reaction in which calcium combines with oxygen?

• CaO

• CaO2

• Ca2O

• Ca2O2
