0.05 1/20 5%
Answer: 9
Step-by-step explanation:
When you multiply 9*9, you get 81 whose sum is 9 (8+1)
Likewise, 9*8=72( 7+2=9)
The first step is to quickly factor each of the five equations... to do so, find the right factors of the 3rd given number so that they add up in an equal number to the second number... 14 = -7 • -2 and -9 = -7 + -2
a^2 - 9a + 14 = 0
(a - 7) (a - 2)
a - 7 = 0, a = 7
a - 2 = 0, a = 2
{2,7}
a^2 + 9a + 14 = 0
(a + 7) (a + 2)
a + 7 = 0, a = -7
a + 2 = 0, a = -2
{-2, -7}
a^2 + 3a - 10 = 0
(a + 5) (a - 2)
a + 5 = 0, a = -5
a - 2 = 0, a = 2
{-5, 2}
a^2 - 5a - 14 = 0
(a - 7) (a + 2)
a - 7 = 0, a = 7
a + 2 = 0, a = -2
{-2, 7}
ok. We are given the following equation:
Where:
Since we are asked to determine "H" we will solve for "H" in the equation. To do that we will first multiply both sides by -1:
Now, we will use the following property of logarithms:
Applying the property and having into account that:
We get:
Now we substitute the given value of "pH = 4.5":
Solving the operation:
Therefore, the hydrogen ion concentration of the fluid is 0.000032
