The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons<span>. Each principal energy level above the first contains one s orbital and </span>three<span> p orbitals.</span>
100 times less H+
A solution at ph 10 contains<u> </u><u>100 times less H+</u> than the same amount of solution at ph 8.
<h3>The pH scale: How does it function?</h3>
- The pH scale determines how acidic or basic water is.
- The range is 0 to 14, with 7 representing neutrality.
- Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
- In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
<h3>How does the pH change when two acids are combined?</h3>
- An acid's strength increases with the quantity of hydrogen ions it releases.
- The pH of the strong acids is between 1 and 2.
- We may observe that there is no response when two acids of the same strength are combined.
- It's because the end product will be neutral and the pH won't change.
<h3>How is pH value determined?</h3>
There are two ways to measure pH:
- colorimetrically with indicator fluids or sheets
- electrochemically with electrodes and a millivoltmeter for greater accuracy (pH meter).

Explanation:
Answer:
895.8g/mol
Explanation:
Hello, here the solution:
Consider the formula for the boiling-point elevation:
We solve for the molality of the solute:
By knowing the mass of the diethyl ether (271.8 g =0.2718kg) and that 11.20g of the solute were dissolved, the molecular mass is given by:
Best regards.
Cooper cannot be broken down into a simpler substance since it is an element meaning it had its own atoms.
