Answer:

1. copper is a pure substance

2. sugar dissolved in solution (sometimes called a homogeneous mixture) is a mixture of sugar and water (the sugar and water don't react with each other)

3. carbon dioxide is a pure substance because there are only CO2 molecules

4. seawater is a mixture of salt, water, and other things
