Answer:
1. B 2. C 3. B or C 4. A 5. A
Answer:
all elements have a different atomic number
Explanation:
Atomic number of element does not affect their reactions with others
Answer:
The difference is 2 pH units.
Explanation:
Let's give an arbitrary value to the H⁺ concentration of solution A, [H⁺]ₐ:
If that's the case then the pH of solution A would be:
----
The H⁺ concentration of solution B ( [H⁺]ₓ ) is 100 higher than that, so:
- [H⁺]ₓ = 0.001 * 100 = 0.1 M
And its pH:
So the difference in pH values is:
Explanation:
option A is the correct answer of this question
The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number.
