Answer:
Non metals are brittle solids.
Explanation:
The option A is correct,
Non metals are brittle solids.
It is the property of non metals. They can not be stretched into thin wire if stress is applied non metals brake down.
All other options are incorrect because,
B = Non metals are often malleable
It is the property of metals. Metals can be malleable into think sheets.
C = Non metals often conduct electricity.
It is the property of metals. Metals conduct electricity because of availability of free electrons.
D = Non metals are often ductile.
It is the property of metals. They can stretched into thin wire.

Explanation:
Answer:
13.53 kJ
Explanation:
The energy of a gas can be calculated by the equation:
E = (3/2)*n*R*T
Where n is the number of moles, R is the gas constant (8.314 J/mol.K), and T is the temperature.
E = (3/2)*3.5*8.314*310
E = 13,531.035 J
E = 13.53 kJ
