The equation for the pH of a substance is where H + is the concentration of hydrogen ions What is the approximate pH of a solution whose hydrogen ion concentration is pH=-log[H^ + ], 2 * 10 ^ - 9

answer: i believe it’s 245.04

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

answer: 177/8
