Answer:
Explanation:
1:) A
Mostly just use context clues
2:) D
The climate on earth is mostly due to earth's atmosphere. So, no, the moon doesn't have similar weather
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
