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
Answer:
I can't say over or under because I don't know the FHA guidelines but they had $2369.98 left over after the housing costs ($1380.02)
Step-by-step explanation:
Expenses for August= 878.65 + 52.50 + 266.67 + 94.52 + 45.03 + 42.65
= $1380.02
Income-Expenses= 3750-1380.02= 2369.98
4)
12/16=21/b
multiply both sides by b
(12/16)b=21
now multiple both sides by (16/12)
b = 21 (16/12) =28
5)
rate is distance / time or time/distance
train travels 279 km per 1.5 hr =270/1.5
or
1.5 hr per 270 =1.5/27p
answer choice a and c matches that.
looking at choice C...270km/1.5hr=5hr/270km
looking at choice A.. 1.5hr/270km=5hr/k km
the units don't match for choice C so the
right answer is A
6)
1.5/270=5/k
multiply both sides by k
(1.5/270)k=21
now multiple both sides by (270/1.5)
k = (270/1.5)21= 900
7) 75 points per 6 game
75 points / 6 games
75/6=P/20
multiply both sides by 20
(75/6)20=P
P=250
