The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the nearest 10th if necessary. Here is the photo of the question

--- Oven Cleaner

--- Water

--- Blood

--- Vinegar

Step-by-step explanation:

The given molar concentration are:[Missing from the question]

Oven Cleaner: [h+] =

Water: [h+] =

Blood: [h+] =

Vinegar: [h+] =

Required

Determine the pH

pH is calculated using:

So, we have:

Oven Cleaner:

Using a calculator, we have:

Water:

Using a calculator, we have:

Blood:

Using a calculator, we have:

Vinegar:

Using a calculator, we have:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely
