The volume of the drum after chilled quickly is 3.6 L.
<u>Explanation:</u>
As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.
After chilling the drum, the volume will get reduced and it can be found as,
V2 =
=
= 3.6 L
Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.
An ionic bond is formed between metal and non metal when they exchange electrons.
The opposing bond would be covalent which is formed between non metal and non metal.
To form an ionic bond, pair any two metal and non metal that will exchange electrons such as LiBr, NaCl, etc.
Hope this helps!
Answer:
Atomic number
Explanation:
Because atomic number is unique for each element and never changes
A. is the answer, because the more an experiment is repeated, it will become apparent if it yields the same results thus confirming or debunking the hypothesis.
