Answer:
B
Explanation:
The normal way to express an energy reaction is to put the energy on the left. Then you can make a rule.
- If the energy on the left is plus then the reactants require energy. The reaction is endothermic -- energy is taken from the environment.
- If the energy is minus when it is on the left. then the reactants give up energy. The reaction is exothermic and energy is given to the environment.
2CO(g)+O2(g) - energy --> 2CO2(g)
Exothermic
Acetone is miscible because it has a C=O bond, while its C-C-C carbon chain makes it miscible with hexane. However, hexane is non-polar while water is polar, and since the two molecules have different polarities, they are immiscible.
