Points A, B, C, and D on the following graph show the energy involved during the reaction process of two different molecules. Below, state what is happening at each position, decide if it is an endothermic or exothermic reaction and tell how you know. What is the name of each phase or state of each letter?

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?

Do polar molecules have ionic bonds?

What is the rate law for the uncatalyzed reaction?
