Answer:
D. All of these
Explanation:
Hi,
So, let's go,
The first thing to know, is that strong acids has a lot of H+ free in solution. While weak acids doesn't have a lot of H+ free.
Now, analyzing the letters
A. Electrical current conduction has a lot of free electrons, so, strong acids has a lot of H+ free in solution too. The combination of these two, in large amount, results in a strong reaction. Very differently with weak acids, which has a few free electrons.
B. ph paper test works with a scale of colors. This means that at one end the acid is strong, and at the other the acid is weak. So, if you drip a drop of the strong acid, the ph paper test will show you different color that when you drop a weak acid.
c. Magnesium is an element from IIA family, that means he reacts strongly with electrons and íons. Which is the cafe os strong acids.
I hope that all questions is solved.
Bye! See ya
