Please someone help me ASAP! I literally posted this question many times and no one is answering! also, PLEASE DO NOT GIVE ME A
RANDOM GIBBERISH ANSWER OR ELSE I WILL REPORT YOU AND GIVE YOU A LOW RATING!!!
If you're unsure of the answer just type it in the comments.
QUESTION:
For the reactivity category, fill in the boxes to indicate how
reactive Helium is . The more filled boxes, the more
reactive Helium is. If helium has 6 valence electrons, how reactive is it?
Also, if all the boxes are filled then helium is very reactive, if not many boxes are filled then its not really reactive.
Just tell me how many boxes I should fill for how reactive the element Helium is!!

The answer for the following problem is mentioned below.
- <u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>
Explanation:
Given:
Initial pressure () = 290 kPa
Final pressure () = 104 kPa
Initial volume () = 18.9 ml
To find:
Final volume ()
We know;
From the ideal gas equation;
P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of gas
n represents the no of the moles
R represents the universal gas constant
T represents the temperature of the gas
So;
P × V = constant
P ∝
From the above equation;
represents the initial pressure of the gas
represents the final pressure of the gas
represents the initial volume of the gas
represents the final volume of the gas
Substituting the values of the above equation;
=
= 52.7 ml
<u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>
