The equation for the pH of a substance is pH = -log[H"], where H+ is the concentration of hydrogen ions. A basic solution has a pH of 11.2. An acidic solution has a pH of 2.4. What is the approximate difference in the concentration of hydrogen ions between the two solutions?

A.) 1.6 x10^-9
B.) 4.0 x10^-3
C.) 6.7 x10^-1
D.) 1.6 x10^11

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
