Answer:
Given:
The pH of solution A = 2.4
The pH of solution B = 9.4.
Solution:
The hydrogen ion concentration is the amount of hydrogen ions present in the given solution usually expressed in terms of moles pere litre .
(A) hydrogen-ion concentrations of the solution.
Now,
The hydrogen ion concentration of the solution A
Similarly
hydrogen ion concentration of the solution B
(b) The hydrogen ion concentration of solution A 
is and the solution B is 
so we can conclude that the hydrogen ion concentration of solution A is 
times greater than solution B
(c) The solutions A and Solution B differ by 7 order of magnitude

B)decreases by one; arrow length decreases by 1/3
She used 54 inches. 3/4 is equal to .75 so you can find 3/4 of the board by taking the fool length and multiplying it by .75 so 6•.75=4.5. So 3/4 of the board is 4.5 ft. However, the answer has to be in inches so since there are 12 inches in a foot you multiply 4.5•12 and that gives you your answer:54 inches.
