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

Which table shows y as DIRECTLY PROPORTIONAL to x
Furkat [3]

Answer:

Table B

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

<em>Verify table B</em>

For x=1, y=1/2 -----> k=y/x=(1/2)/1=1/2

For x=2, y=1 -----> k=y/x=1/2

For x=3, y=3/2 -----> k=y/x=(3/2)/3=1/2

For x=4, y=2 -----> k=y/x=2/4=1/2

The values of k are the same

therefore

The table B shows y as DIRECTLY PROPORTIONAL to x

<em>Verify table D</em>

For x=1, y=3 -----> k=y/x=3/1=3

For x=2, y=5 -----> k=y/x=5/2=2.5

For x=3, y=7 -----> k=y/x=7/3

For x=4, y=9 -----> k=y/x=9/4

the values of k are different

therefore

The table D not shows y as DIRECTLY PROPORTIONAL to x
