Assuming there is enough acetic anhydride available, then both OH groups will be acetylated to give their acetate esters (OCOCH3). Use a drop of sulfuric acid as the catalyst.</span>
First box is where the Sun's energy is produced. The second box is hot gases move up and cool gases sink down. Then Region of the Sun that is visible from Earth. Last is appears as a red ring around the Sun right before and after the peak of a total solar eclipse. I hope this helps!
Answer:
Point 3 for kinetic, points 1 and 5 for potential
Explanation:
There is one point that the ball has the most kinetic energy it is at point 3. Point 3 has the most kinetic energy because it has gained the most speed since it was dropped and it also is right before it starts slowing down from trying to go up again. Points 1 and 5 have the most potential energy. When the ball is at point 1 or 5 it is at its maximum height thus it cannot swing any further, so it stops for a split second and gains a large amount of potential energy before it is released into kinetic energy when it falls back down.
