When testing the effect of caffeine on cardiac rate, Valerie used water fleas as her test subject. She placed 5 water fleas ia beaker #1 with 50 mL normal water,
then placed 5 water fleas in beaker #2 with 1 mL coffee and 50 mL water, 5 water
fleas in a petri dish with 5 mL coffee and 50 mL water, and 5 water fleas 10 mL of
coffee and 50 mL of water. In the experiment above, what is the purpose of
beaker #1? *

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

your answer would be “dry”
