Hope this helps.
Answer:
8.085x10²¹ atoms
Explanation:
Atomic mass of Fe = 55.845 g/mol
it means ,
1 mole Fe = 55.845 g
1 mole = 6.02x10²³ atoms
so,
55.845g Fe has = 6.02x10²³ atoms
∴0.750 g Fe has = {(6.02x10²³ x 0.750)/55.84} atoms
=8.085x10²¹ atoms
I can help you but what is the question here?
Answer:
A. it is the lowest at low temperatures
Explanation:
It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.
The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.
- Kinetic energy is directly proportional to the temperature of a substance.
- The higher the temperature, the more the kinetic energy of the molecules within a system.
- At low temperature, kinetic energy is the lowest.
- At the highest temperature, kinetic energy is the highest
