The ingredients that is important in making plastics is natural gas plant liquids.
Natural gas liquids (NGLs) are components of natural gas which are separated from the gas state in the form of liquids. They many applications including; plastic production, inputs for petrochemical plants, they are also burned for space heat and cooking, and can also be blended into vehicle fuel.
In the manufacturing of plastics, come components of NGLs are used. And for this case, ethane. Ethane is used in the production of ethylene which are passed through pressure and catalyst to be turned to plastics like polythene.
The reason why they are mostly used in the manufacturing plastics than other resources like crude oil is that it is much cleaner.

Answer:
The standard enthalpy of formation of NOCl(g) at 25 ºC is 105 kJ/mol
Explanation:
The ∆H (heat of reaction) of the combustion reaction is the heat that accompanies the entire reaction. For its calculation you must make the total sum of all the heats of the products and of the reagents affected by their stoichiometric coefficient (number of molecules of each compound that participates in the reaction) and finally subtract them:
Enthalpy of the reaction= ΔH = ∑Hproducts - ∑Hreactants
In this case, you have: 2 NOCl(g) → 2 NO(g) + Cl₂(g)
So, ΔH=
Knowing:
- ΔH= 75.5 kJ/mol
= 90.25 kJ/mol
= 0 (For the formation of one mole of a pure element the heat of formation is 0, in this caseyou have as a pure compound the chlorine Cl₂)
=?
Replacing:
75.5 kJ/mol=2* 90.25 kJ/mol + 0 -
Solving
-=75.5 kJ/mol - 2*90.25 kJ/mol
-=-105 kJ/mol
=105 kJ/mol
<u><em>The standard enthalpy of formation of NOCl(g) at 25 ºC is 105 kJ/mol</em></u>
