A measure of the kinetic energy of particle motion within a substance is _____.
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
It is known that energy obtained by an object due to its motion is known as kinetic energy. Whereas an energy obtained by an object due to its position is known as potential energy.
For example, when water is heated then bond between its molecules starts to break and therefore, molecules start to move as they tend to gain kinetic energy due to increase in temperature.
Also, it is known that K.E =
where k = boltzmann constant
T = temperature
Hence, kinetic energy is proportional to temperature. So, more is the increase in temperature more will be the increase in kinetic energy.
Thus, we can conclude that a measure of the kinetic energy of particle motion within a substance is temperature.

Answer:
4.1 moles of FeCl₃
Explanation:
The reaction expression is given as shown below:
2Fe + 3Cl₂ → 2FeCl₃
Number of moles of Cl₂ = 6.1moles
So;
We know that from the balanced reaction expression:
3 moles of Cl₂ will produce 2 moles of FeCl₃
Therefore 6.1moles of Cl₂ will produce = 4.1 moles of FeCl₃
The number of moles is 4.1 moles of FeCl₃
