Question 3(multiple choice worth 4 points) (08.04 lc) which of the following happens to an acid when it reacts with another substance? it receives a hydrogen ion. it receives a hydroxide ion. it donates a hydroxide ion. it donates a hydrogen ion.

It donates a hydrogen ion

Explanation:

Under the Bronsted-Lowry definition of an acid, acids are protons donors which donate the H+ ion, or the hydrogen ion.

The correct option is "it donates a hydrogen ion"

Explanation:

The choice for the last option being the correct answer is because of the Bronsted-Lowry definition of an acid. Bronsted-Lowry acid is a substance that donates a hydrogen ion or a proton.

Consider the reaction below

HCl + NH₃  ⇒ NH₄⁺ + Cl⁻

From the above, we can see that HCl is an example of Bronsted-lowry acid since it donates its hydrogen ion to NH₃ to form NH₄⁺

Atomic radius of copper atom (r)= 128 pm

volume of sphere = 4/3 * pi * r^3 = 4/3 * 3.14 * 128^3

volume = 8780076.373 pm^3
