What will happen If you add two drops of nonpolar red dye to a 2 mL cyclohexane solution? * a red homogenous solution will form a red heterogenous solution will form the color of solution will change from red to colorless the solution will still remain colorless

1. One common chemical contaminant that is removed from water during water treatment. How is it removed and why? Include chemical formulas and chemical reactions. 2. One chemical that is added to water during water treatment. How is it added to water and why? Include chemical formulas and chemical reactions.

6. Suppose you have a mixture of water and your 2-bromo-2-methylbutane product in a separatory funnel. Use densities to predict which phase will be the top layer in the funnel. a. 2-bromo-2-methylbutane (organic phase) b. water (aqueous phase) c. there would only be one phase since the substances are miscible
