C) Decreasing the Temperature

The correct option is this: DECREASING THE TEMPERATURE.

During the process of chemical reaction, the reacting molecules typically move about randomly in the reacting vessels colliding with one another and with the wall of the container. The rate of movement of the reacting particles can be reduced by decreasing the temperature of the reaction. If the temperature is reduced, the particles will lose kinetic energy and thus, they will move more slowly and collide less often with one another.

How many moles are in a sample of 1.52 x 1024 atoms of mercury (Hg)?
OLEGan [10]

The answer is:

2.5 moles

The explanation:

when avogadro's number = 6.02 * 10^23

and when 1 mole of the sample will give → 6.02*10^23 atoms

So,        ??? mole of the sample will give→ 1.52 x 10^24 atoms

∴ number of moles = (1.52 X 10^24) * 1 mole / (6.02X10^23)

                                = 2.5 moles
