Answer:
Light
Explanation:
1 They were not albe to see at night because it was dark so the lack of light caused them to use echolocation.
Hope this helps

The given compound has 3 carbon atoms, so in 1 mole of that compound, there will be 3 moles of carbon atoms.
Mass of each mole of carbon atoms = 12 g
For 3 mole carbon atoms, it will be 12 × 3 = 36 grams

Slow chemical change
It is a chemical change because the erosion is due to the chemical reaction between the acid and the in the rain and the calcium carbonate.
It is slow due to the concentration of acid is low.
One mole of hydrogen peroxide contains 6.02 x 10^23 molecules of hydrogen peroxide. And each molecule contains 4 atoms, so the answer is 4 x 6.02 x 10^23.
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.
