The equation for the ph of a substance is PH equals negative log H +, where H + is the concentration of hydrogen ions. What is the approximate ph of a solution if the concentration of hydrogen ions is 5.1 × 10 to the power of negative for moles per liter

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
