Answer:
4 atoms of Chlorine
Explanation:
This is actually easy to explain,
First we have here a type of nomenclature. This one is the sistematic nomenclature, and begins by naming the number of atoms that one element has, beggining for the non metal first, and then the metal or the non metal acting like a metal. In this case, the Carbon is acting like a metal.
The number of atoms are named by a prefix of the number. Each number has a determined prefix. Here are some of them:
one = 1 = mono
two = 2 = bi or di
three = 3 = tri
Four = 4 = tetra
Five = 5 = penta
Six = 6 = Hexa
So tetrachloride, means that we have 4 atoms of chlorine in the molecule and the molecule is this one: CCl4
The precaution to be taken while measuring the temperature of a liquid in a beaker is applying proper heat balance and taking all the required precautions.
- A beaker with an open top contains a sample of liquid. It exposes this sample to light.
- That liquid absorbs the light energy, turning it into heat energy. As a result, the liquid becomes warmer and evaporation is accelerated. As a result, there is less liquid in the beaker.
- Since it is well known that the surface temperature of a liquid, along with air movement above the liquid surface, is one of the dominant factors affecting evaporation, I want to measure the evaporation rate as a function of surface temperature.
- This can be done by applying a heat balance.

The temperature of a certain substance can be seen as the average speed of the atoms or molecules in that substance. In the liquid state of a substance the forces between the atoms or molecules are strong enough to keep them together, however with enough freedom to move, unlike in the solid state. If we would have a closer look at the surface of a liquid from sideways, we would see water molecules jumping out of the water and reentering it again. The lower the water temperature would be the lesser the amount of water molecules leaving the liquid phase would be. If water would be heated up and the temperature will reach 100 degrees C at normal atmospheric pressure, more water molecules would leave the water than reentering. Boiling has started. The temperature of the water remains at 100 degrees C, if the heating continues as the average speed of molecules will not increase, only the rate of molecules leaving the water will increase, until all the water in liquid state has been vapourized. The amount of heat needed to vapourize liquid water is called latent heat. Latent heat is a very important driving factor in the atmosphere and thus the weather.
Metals are insulators and malleable. Hope this helps even though I'm late :)
The molar mass of CuCl2 is 134.45 g/mol; therefore, you divide 2.5 g of CuCl2 by 134.45 g of CuCl2 leaving you with 0.019 moles
