For these problems we need to distribute first and then combine like terms. We can add anything with an "x" together and anything without an "x" together.

Problem 1:

2(x-1)+3(x+2)
2x - 2 + 3x + 6
Answer: 5x + 4

Problem 2:

(4y-3)-2(y-5)
4y - 3 - 2y + 10
Answer: 2y + 7

A container of orange juice has a pH of 3.3. Find the concentration of hydronium ions in the milk.
kap26 [50]

The concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if  the container of orange juice has a pH of 3.3.

<h3>What is pH value?</h3>

The pH of a solution is a measurement of the concentration of hydrogen ions in the solution, as well as its acidity or alkalinity. Normally, the pH scale ranges from 0 to 14.

We have:

A container of orange juice has a pH of 3.3.

The pH value = 3.3

\rm pH = -log[H_3O^+]

\rm 3.3 = -log[H_3O^+]

Removing log:

\rm 10^{-3.3}=[H_3O^+]

\rm [H_3O^+] = 5.011\times10^{-4}

Thus, the concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if  the container of orange juice has a pH of 3.3.
