The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the near

svet-max [94.6K]

Explanation:

Formula to calculate pH of a chemical or solution is as follows.

pH = $-log [H^{+}]$

Therefore, calculate the pH of given chemicals as follows.

1). Oven cleaner

pH = $-log [H^{+}]$

= $-log [10^{-13}]$

= 13

2). Water

pH = $-log [H^{+}]$

= $-log [7 \times 10^{-7}]$

= 6.15

3). Blood

pH = $-log [H^{+}]$

= $-log [4 \times 10^{-8}]$

= 7.40

4). Vinegar

pH = $-log [H^{+}]$

= $-log [63 \times 10^{-4}]$

= 2.20

The measure of an angle that is its own supplement is

kipiarov [429]

Answer: 90 degrees

============================

Explanation:

Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.

Consequently, we can replace y with x and solve for x like so:

x+y = 180

x+x = 180 .... y is replaced with x since y = x

2x = 180

2x/2 = 180/2

x = 90

This means y = 90 as well. As a check, note how

x+y = 90+90 = 180

which verifies our answer.
