The answer is, D. Calcium
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>

Elements are made of only one kind of atom. The molecule is made up of two or more kinds of atoms. There is no physical change that can separate the compounds into more than one kind of substance. This makes a compound a pure substance.
