A solution with a pH of 13.8 means that the solution is a strong base.
<h3>What is pH?</h3>
pH refers to power of hydrogen. The pH is a scale used to measure the degree of acidity or alkalinity of a solution.
pH scale ranges from 0 - 14
Where;
- 0 -6.9 indicates acidic
- 7.1 - 14 indicates basic
However, the closer the pH value is to 1, the more the acidity and vice versa while the closer it is to 14, the more the alkalinity and vice versa.
Therefore, a solution with a pH of 13.8 means that the solution is a strong base.

Answer:
Clouds are formed when water warms up and changes into a gas called water vapor, which rises up into the air.
Explanation:
A vacuum: the motor starts the fan that causes the vacuum to have suction and the motor is what moves the bristles

Answer:
1.32 x 10²⁴
Explanation:
Given parameters:
Volume of carbon tetrachloride = 49.3L
Unknown:
Number of atoms at STP = ?
Solution:
To solve this problem;
At STP;
1 mole of a substance occupies 22.4L ;
So;
Let us find the number of moles;
22.4L = 1 mole
49.3L will give = 2.2mole
So;
1 mole of substance contains 6.02 x 10²³ atoms
2.2 mole of Carbon tetrachloride = 2.2 x 6.02 x 10²³ = 1.32 x 10²⁴
Cyclopentane is NOT an isomer of pentane.
Isomers must have the same molecular formula.
The molecular formula of pentane is C₅H₁₂, while the molecular formula of cyclopentane is C₅H₁₀.
The two molecules cannot be isomers.
