Wait what. Since when did we need to know that kinda stuff???

We don't, she just asked what salt forms with calcium carbonate and Hcl so I'm guessing it's just calcium chloride

No. Crude Oil is just a mixture of chemical compounds I swear? You don't break down Polymers, all I know is from the Alkenes, you have individual strands called monomers and you put them together to get Polymers which is called Polymerisation.

I'm not sure to be honest but here is some important info

What is Distillation?
Distillation is when we make a liquid evaporate and then condense the vapour back to a purer liquid.

What does Unsaturated mean?
An unsaturated compound contains at least one double or triple bond.

What is a Hydrocarbon?
Hydrocarbons are a group of compounds which contain elements of hydrogen and carbon.

What is a Catalyst?
A catalyst changes the rate of a chemical reaction without having being changed by the reaction itself.

What is thermal decomposition?
A reaction in which substances are broken down by heat.

I hope I helped also

also a catalyst speeds up the rate of reaction
