If calcium carbonate decomposes, the product of the reaction would be calcium oxide and carbon dioxide.
Balanced chemical reaction: CaCO₃(s) → CaO(s) + CO₂(g).
CaCO₃ is calcium carbonate.
CaO is calcium oxide
CO₂ is carbon dioxide or carbon(IV) oxide
Chemical decomposition is the separation of a single chemical compound (in this example calcium carbonate) into its two or more simpler compounds (in this example calcium oxide and carbon dioxide).
Decomposition is reaction where one substance is broken down into two or more simpler substances. Heat is usually necessary to this type of reaction.

the line graphs and pie charts are used for different kinds of analysis
a) pie chart : it compares the portion of one thing in a group of different things
For example out of 100 people how many have brown hairs , how many have black hairs and how many have white hairs
or
like population division out of 100 into different parts
b) line graphs: they show the relation ship between two variables
Example: effect of temperature on volume
it tells the trend in any property with respect to some other quantity or quality parameter.

<span>In a laboratory experiment, John uses a mesh to separate soil particles from water. Which technique of separation is he using?
The technique that John is using is the filtration technique. Filtration is a technique to separate the solid which is insoluble from the liquid. For instance: Sand and water, sand is insoluble, thus it stays in the filter paper, while the water proceeds through the filter paper.
Hope I helped :D</span>

Answer : The final volume of gas will be, ![2.36\times 10^9L](https://tex.z-dn.net/?f=2.36%5Ctimes%2010%5E9L)
Explanation :
Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
![V\propto T](https://tex.z-dn.net/?f=V%5Cpropto%20T)
or,
![\frac{V_1}{V_2}=\frac{T_1}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BV_1%7D%7BV_2%7D%3D%5Cfrac%7BT_1%7D%7BT_2%7D)
where,
= initial volume of gas = ![2.74\times 10^9L](https://tex.z-dn.net/?f=2.74%5Ctimes%2010%5E9L)
= final volume of gas = ?
= initial temperature of gas = ![20.0^oC=273+20.0=293K](https://tex.z-dn.net/?f=20.0%5EoC%3D273%2B20.0%3D293K)
= final temperature of gas = ![-20.0^oC=273+(-20.0)=253K](https://tex.z-dn.net/?f=-20.0%5EoC%3D273%2B%28-20.0%29%3D253K)
Now put all the given values in the above formula, we get the final volume of the gas.
![\frac{2.74\times 10^9L}{V_2}=\frac{293K}{253K}](https://tex.z-dn.net/?f=%5Cfrac%7B2.74%5Ctimes%2010%5E9L%7D%7BV_2%7D%3D%5Cfrac%7B293K%7D%7B253K%7D)
![V_2=2.36\times 10^9L](https://tex.z-dn.net/?f=V_2%3D2.36%5Ctimes%2010%5E9L)
Therefore, the final volume of gas will be, ![2.36\times 10^9L](https://tex.z-dn.net/?f=2.36%5Ctimes%2010%5E9L)
