How is ethene obtained from ethanol?

What will be the condensed structure of PVC? Write any four uses of PVC.

Nadira was studying the chemical properties of ethanol and ethanoic acid. To do this, she took ethanoic acid and concentrated sulphuric acid in a test tube and heated the mixture. While she was carrying out this activity, Meena came and added ethanol to the mixture. When this mixture was added to water, there was a unique odour. Can you tell which chemical reaction took place and write the balanced equation for the reaction.

Abraham had two solutions - ethanol and ethanoic acid. He added sodium to both the solutions and saw that a gas was produced. When a burning matchstick was placed near the gas, a pop sound was heard. Show the reactions through chemical equations. 

Jaspreet has ethanol and ethanoic acids in two separate beakers but she forgot to label them. Help Jaspreet identify which beaker has ethanol and which has ethanoic acid. 

What is a polymer? Explain the polymerization of ethene.

What is the difference between low density polythene and high density polythene? Write their uses based on their properties. 

When a carbon compound, A having molecular weight $46 \mathrm{u}$ was oxidized, a carbonic acid B was obtained. Compound A is used a sterilising agent. Identify A and B and write the balanced chemical equations.
