2.2 Dichloroethane, CzH4Cl2, is used to prepare chloroethene. Chloroethene is a monomer which is used to make polyvinylchloride (PVC) as follows:
C2H4Cl2 - CH3CI + PVC
Reaction 1 Reaction 2
2.2.1 Write down the name of reaction 1. (1)
2.2.2 Write balanced structural formulae to represent reaction 1. (3)
2.2.3 Write down the name of reaction 2.
2.2.4 Write the structure of PVC showing two repeat units. (2)​

10 years is the answer

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

i believe the answer is 5,000
