What is the hydronium ion (H3O+) concentration in milk if it has a pH of 8.2?

valkas [14]

The hydronium ion is H₃O⁺ and its concentration is equivalent to the H⁺ ion concentration. The H⁺ ion concentration is given by:

pH = -log[H⁺]
[H⁺] = 10^(-8.2)
[H⁺] = 6.31 x 10⁻⁹ mole/dm³

The hydronium ion concentration is 6.31 x 10⁻⁹ mole/dm³

The hypotenuse of a right triangle is 26 mm. One leg of the right triangle is 10 mm. What is the length of the other leg? (4 poi

PIT_PIT [208]

Answer:

24 mm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagorean theorem

$a^2+b^2=c^2$

where a and b are the legs, and c is the hypotenuse.

We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.

$10^2+b^2=26^2$

Solve the exponents

$100+b^2=676$

Now, solve for b. To do this, get b by itself.

First, subtract 100 from both sides

$100-100+b^2=676-100$

$b^2=576$

Take the square root of both sides

$\sqrt{b^2}=\sqrt{576}$

b=24

So, the other leg is 24 mm
