Answer:
<h2>Volume = 6 cm³</h2>
Explanation:
Density of a substance is given by

From the question
Density = 4.0 g/cm³
mass = 24g
Substitute the values into the above formula and solve for the volume
That's

Divide both sides by 4
v = 6
We have the final answer as
<h3>Volume = 6 cm³</h3>

Answer:
hydroxide ion
Explanation:
because base produce hydroxide ion when dissolved in water
Answer:
See figure 1
Explanation:
If we want to find the acid and the Brønsted-Lowry base, we must remember the definition for each of these molecules:
-) Acid: hydrogen donor
-) Base: hydrogen acceptor
In the <u>caffeine structure,</u> we have several atoms of nitrogen. These nitrogen atoms have the ability to <u>accept</u> hydronium ions (
). Therefore the caffeine molecule will be the base since it can accept
If caffeine is the base, the water must be the acid. So, the water in this reaction donated a hydronium ion.
<u>Thus, caffeine is the base and water the acid. (See figure 1)</u>
B because A is for radios of course and C is thermal energy and D is radioactive
