1. The pH of the solution is 1.36
2. The pH of the solution is 10.47
3. the concentration of [H₃O⁺] in the solution is 6.3×10⁻¹⁴ M
<h3>What is pH ? </h3>
This is simply a measure of the acidity / alkalinity of a solution.
The pH measures the hydrogen ion (hydronium ion) concentration while the poH measures the hydroxide ion concentration. It is expressed mathematically as
pH = –Log H₃O⁺
<h3>1. How to determine the pH</h3>
- [H₃O⁺] = 4.32×10⁻² M
- pH = ?
pH = –Log H₃O⁺
pH = –Log 4.32×10⁻²
pH = 1.36
<h3>2. How to determine the pH</h3>
- [H₃O⁺] = 3.4×10⁻¹¹ M
- pH = ?
pH = –Log H₃O⁺
pH = –Log 3.4×10⁻¹¹
pH = 10.47
<h3>3. How to determine the concentration of [H₃O⁺]</h3>
pH = –Log H₃O⁺
13.2 = –Log H₃O⁺
Multiply through by -1
-13.2 = Log H₃O⁺
Take the anti-log of -13.2
H₃O⁺ = anti-log (-13.2)
H₃O⁺ = 6.3×10⁻¹⁴ M

Answer:
D. Blueberry plants grow at a faster rate in acidic soil than in basic
soil.
Explanation:
Avagadros number is where 1 mol of any substance is made of 6.022 x 10²³ units. These units could be atoms making up an element of molecules making up a compound.
1 mol of Br₂ is made of 6.022 x 10²³ molecules of Br₂
the flask contains 0.100 mol
Therefore if 1 mol has 6.022 x 10²³ molecules of Br₂
then 0.1 mol has - 6.022 x 10²³ molecules/mol x 0.1 mol
therefore number of molecules - 6.022 x 10²² Br₂ molecules ₂
Bef2 is the compound that has the most covalent character. Whichever element has the greatest electronegativity has the least difference and most covalent character.
