Which way does the ion move and why? Na+ F=23100 cal/V*mol Vm = -60mV R =2cal/mol*K T = 300K Inside 50mM Outside 150mM   A. Into the cell due to charge and concentration   B. Out of the cell due to charge and concentration   C. Out of the cell due to charge   D. Into the cell due to concentration.

To explain: The reason why the movement of H* ions is faster than Ca²* ions. Also how this speed would be 2+ affected if solution was frozen.

Electrically neutral molecules can pass through cell membranes more easily than charged molecules can. Aspirin has a carboxylic acid group with a pKa value of 3.5. In order to be absorbed into the bloodstream it must pass the membrane lining the stomach and intestine. Would you expect more aspirin to be absorbed in the stomach (pH 1) or in the small intestine (pH 6)?

When two drops of NaOH were added to the water the color changed from purple to green. Did this make the pH: Increase stay the same decrease a lot decrease  When HCI was added to water, the color changed from purple to hot pink. Did this make the pH: Increase stay the same decrease a lot decrease
