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?​

What is the relationship between the wavelength of a wave and it's energy?

Player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 26 m/s. what is the horizontal velocity component of the ball to the nearest tenth of a m/s?

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.
