So for this problem, we want to write out the chemical equation for the formation of carbon tetrachloride from methane and chlorine gas.
00:08
So let's begin by writing out our reactants and products.
00:12
For our reactants, we have methane, which is written out as ch4, and chlorine gas.
00:19
Remember that chlorine is a halogen, and in this gaseous form, it is naturally diatomic, so there are two chlorine atoms.
00:27
And our product is carbon tetrachloride.
00:30
This is a covalent compound, so we follow the latin root prefixes.
00:36
So carbon tetrachloride, tetra is lined for four, so there are four chlorine atoms.
00:42
And carbon does not have a latin root affixed to it, so we assume it's mono, therefore there's only one carbon.
00:48
So now we specify our states of matter.
00:51
Methane is naturally a gas, and it states is a gas, so we write the notation for gas...
