Answer: The correct answer is option B.
Explanation: There are 7 elements in group VIII-A. They are Helium (He), Neon(Ne), Argon(Ar), Krypton (Kr), Xenon (Xe), Radon (Rn) and Ununoctium (Uuo). They are considered as a part of group 18.
Metals are shown in purple color in the periodic table. Metalloids as blue color and Non-metals are shown in green color.
Group VIII-A elements have fully filled orbitals and hence are most stable amongst all the elements in the periodic table. They are considered as least reactive elements and as they are categorized as non-metals. So, they are the least reactive non-metals.
Therefore, the correct option is B.
Answer:
Volume of the gas at 44°C is <u>258 ml.</u>
Explanation
here,
using Charles' law ,
where , V= initial volume v= final volume
T=initial temperature t = final temperature
Given - pressure is constant ,
so , putting the values -
V= 240ml
T= 22 + 273K = 295K (since converting celsius into kelvin that
is +273K )
v =?
t = 44+ 273K = 317K
Now , putting the given values in charles' law ,
240ml x317K = v x 295K (through cross multiplication )
v =
= 258ml .
thus ,<u> the volume of carbon dioxide in a container at 44°C IS 258ml .</u>
