Which statement is true about a solution that has a ph of 12?
a. it is abnormal.
b. it is acidic.
c. it is alkaline.
d. it is neutral.

The pH of a solution has a range of 1-14. The neutral solution is at pH 7. The lower range below 7 is the acidic region. On the other hand, the upper range above 7 is the basic region.  Thus, a pH of 12 is a basic or alkaline solution. The answer is C.

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.

The mole ratio of hydrogen to ammonia is 3: 2.
