PH and pOH Formulas
Concentration Formulas
pH = -log[H30)
[H30*) = 10-PH
pOH = -log(OH)
[OH] = 10-POH
pH + POH = 14.00
[H3O+][0] = 1.0 10-14
What is the hydronium (H30*) concentration of a solution with a pH of 3.60?
A 2.5 x 10^M
B 3.0 x 10-M
C 4.0 x 10M
D.
45* 10-11M

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?

What will most likely happen in the absence of a cell membrane? a) photosynthesis will not take place. b) the cell will not store food, water, nutrients, and waste. c) energy will not be released during cellular respiration. d) substances will pass in and out of the cell in an uncontrolled manner.
