Answer:
pH = 10
The solution is basic.
Explanation:
A solution contains 1 × 10⁻⁴ M OH⁻ ions. First, we will calculate the pOH.
pOH = -log [OH⁻]
pOH = -log 1 × 10⁻⁴
pOH = 4
We can find the pH of the solution using the following expression.
pH + pOH = 14.00
pH = 14.00 - pOH = 14.00 - 4 = 10
Since the pH > 7, the solution is basic.
The battery itself contains chemical energy, which is converted to electrical energy, and then converted to mechanical energy.
<span>The question says,'Mathew was working with different concentrations of hydrochloric acid in the lab. Which of these would best describe the resulsts Mathew would see if he was using a conductivity apparatus in each of the different acid concentration. The correct answer is C. This is because, acids conduct electricity, the stronger the acid, the brighter the electricity that will be produced while the weaker the acid, the weaker the electricity that will be produced. Thus, higher concentration equals tronger electricity.</span>
It is a chemical <em>process</em> - an oxidation.
