In its aqueous solution, 99.9% of a substance dissociates to release hydronium ions. which of the following is true for the substance?
it is a weak acid.
it is a weak base.
it is a strong acid.
it is a strong base.

It is a strong acid.

Explanation:

A strong acid is any acid that is completely ionized in solutions to release the greatest number of hydronium ions or protons when placed in a solution.

So, when 99.9% of a substance dissociates to release hydronium ions. It is considered as a strong acid.

It is a strong acid

Explanation:

I just took the test and got it right.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
