The rate law for the decomposition of phosphine (ph3) is below. it takes 120. s for 1.00 m ph3 to decrease to 0.250 m. how much time is required for 4.00 m ph3 to decrease to a concentration of 0.320 m?

Asolution of sodium hydroxide was titrated against a solution of sulfuric acid. how many moles of sodium hydroxide would react with 1 mole of sulfuric acid?

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?
