Answer:
C. A reaction that absorbs heat
Explanation:
I do not know Latin, but roughly speaking 'Endo' means inside, and 'thermic' means heat.
Unlikely. It's unlikely for ammonium ion
to accept a proton
and act as a Bronsted-Lowry Acid.
<h3>Explanation</h3>
What's the definition of Bronsted-Lowry acids and bases?
- Bronsted-Lowry Acid: a species that can donate one or more protons
in a reaction.
- Bronsted-Lowry Base: a species that can accept one or more protons

Ammonium ions
are positive. Protons
are also positive.
Positive charges repel each other, which means that it will be difficult for
to accept any additional protons. As a result, it's unlikely that
will accept <em>any</em> proton and act like a Bronsted-Lowry Base.
The scientific form is

So, the form of scientific notation is
