Answer: kinetic
Explanation:
Kinetic energy is the energy possessed by an object by virtue of its motion.
Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:
K= kinetic energy
R= gas constant
T= temperature
From above, it is visible that kinetic energy is directly related to the temperature of the system. So, if average kinetic energy of the system increases, the temperature of the system will increase.
Answer : 6.41 moles of silicon are in the sample.
Solution : Given,
Moles of magnesium = 9.62 moles
The given chemical formula for talc is,
From the given chemical formula we conclude that
The stoichiometry of magnesium and silicon is 3 : 2
3 moles of magnesium is equivalent to 2 moles of silicon
9.62 moles of magnesium will be equivalent to moles of silicon
Therefore, the number of silicon present in sample are 6.41 moles.
