HU: Le Châtelier's principle applies to gas exchange reactions in human lungs. Carbon dioxide gas combines with water in the blood to form carbonic acid: H2O + CO2 ⇄ H2CO3. When you breathe more rapidly, the concentration of CO2 in your blood decreases. How would this affect the concentration of H2CO3?

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
