7. Which of the following supports the conclusion that a chemical reaction has occurred? Adding salt to a salt water solution results in salt settling to the bottom of beaker Heating a salt solution on a hot plate raises its temperature. Shining a flashlight through a beaker salt solution causes refraction of the liquid. Adding an acid to a salt solution raises temperature.

16. A beach ball rests on the sand. When the wind blows, the ball rolls away. Which statement correctly assesses the reason for this change in motion? The ball moved because an unbalanced force acted upon it. The ball moved because a balanced force acted upon it. The ball moved because the force of gravity was overcome. The ball moved because there was no friction to overcome.

28. In lab, Paul added a small amount of a solid cobalt salt to his reaction vessel. The cobalt salt was added to catalyze the chemical reaction. While he was pouring the salt into the test tube, he spilled a small amount onto the countertop. Which of the following factors is least likely to be affected by the spillage of salt? Paul's ability to replicate his results. Paul's ability to interpret his data. The equipment needed for the experiment. The accuracy of Paul's data

30. The equipment needed for the experiment.

31. In lab, Paul added a small amount of a solid cobalt salt to his reaction vessel. The cobalt salt was added to catalyze the chemical reaction.
