Plzzz help In this activity you will complete a virtual experiment to determine how the temperature of water affect the time it takes for antacid tablets to dissolve. Read over the lab report before you begin. If you choose to conduct this experiment by setting it up at home, then please review the lab safety guide in the Course Information section before you begin. Keep in mind you may use the video in the lesson to record the reaction times. Pre-lab Questions: (10 points)
questions
1. How does an increase in concentration affect a chemical reaction?
2. When temperature increases, what happens to the molecules in a chemical reaction?
3. How do we measure the average kinetic motion of molecules in a solution?β

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
