Answer:
Correc option:
Explanation:
size of atom : it says somthing about how many shell present in a particular atom or ion and it can also be evaluated on the basis of radius of atom.
Br^- and Kr has highest number of shell as compared to other group of species .
Na ,S , Mg ,P all are from 3rd period but Kr and Br^- in the 4th period so size of species of this group will more,
Size increases on increasring the shell number
525L
Explanation:
Given parameters:
Volume to Temperature ratio = 1.75
Temperature = 300k
Unknown:
Volume of the gas = ?
Solution:
We must carefully analyze and comprehend the detailed description of this experiment:
It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.
This implies that the pressure in the vessel is constant
This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.
Mathematically;
V and T are the volume and temperature
Now we can solve the given problem;
= 1.75
Since temperature is given as 300K
Input the variables:
= 1.75
V = 1.75 x 300 = 525L
