15.1g per day of a certain industrial waste chemical P arrives at a treatment plant settling pond with a volume of 10,000m3. P is destroyed by sunlight, and once in the pond it has a half-life of 23.h. Calculate the equilibrium concentration of P in the pond. Round your answer to 2 significant digits.

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?

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?
