Polythene or more correctly named polyethene is a compound of ethene that has undergone addition polymerisation. So yes, it is a compound. An acid is a compound that can donate protons (H+) A element is a 'pure' form that contains just the element it's self. They are all listed on the Periodic Table A compound is a substance made up of different elements that are all chemicaly bonded together. (By either ionic or covalent bonds) A mixture is a 'mix' of different compounds or elements that are not bonded together.

(Car) Battery acid is a compound. It is sulphuric acid. In a car battery lead(Pb) and copper(Cu) plates are immersed in sulphuric acid. When there is an electrical discharge across the battery , internally, the sulphuric acid reacts with the lead (Pb) plate. Seen as a white powder at the battery terminals, especially when the battery is old. There is also a release of hydrogen gas. There should be a 'vent' tube to release the hydrogen. Because if a (electrical)spark goes across the hydrogen , the battery explodes. When this lead sulphate increases on the lead plate, it will eventually touch the copper plate. The battery immediately discharges and will not work. So you have to replace the battery. H2SO4 + Pb = PbSO4 + H2 H2 + (1/2)O2(air) == spark/bang ==> H2O
It is a compound of hydrogen, sulfur and oxygen.
Sulfuric acid is a compound
Acetic acid is a compound composed of carbon, hydrogen, and oxygen atoms. It is not an element or a mixture, but a pure substance with a specific chemical formula (C2H4O2).
Sulfuric acid is a compound, not a mixture or an element. It is composed of sulfur, oxygen, and hydrogen atoms chemically bonded together in a specific ratio to form the compound H2SO4.
Hydrochloric acid has the chemical formula HCl. It is a compound.
Folic acid is a compound, not an element. It is a form of vitamin B9 that is essential for cell growth and metabolism.
Vinegar is a compound and a mixture, being mainly acetic acid (compound)mixed into water (another compound).
