The element from those four that is a noble gas is krypton.
The correct answer is:
They have a low boiling point because of weak intermolecular forces.
Answer:
The answer will be A
Explanation:
A scientific law is based on repeated experiments or observations, that describe or predict a range of natural phenomena. A scientific law is something that is unexpected
582 ml is the volume of gas.
Answer:
Explanation:
Using the ideal law of gases, the kinetic theory of gas can be stated as
PV = nRT
Here P is the pressure and it is given as 1.2 atm, V is the volume, which we need to find. Then R is the gas constant and T is the temperature while n is the concentration present.
As per the give question, P = 1.2 atm, T = 140 K and n = 0.5 moles, R = 8.314
V = 
V = 
So 582 ml is the volume of gas.
