Lead nitrate is a compound, as it is composed of lead, nitrogen, and oxygen atoms that are chemically bonded together in a specific ratio. It is not considered an element or a mixture because it is a pure substance with a fixed composition.
No, energy is NOT an element, a compound or a mixture.
electricity is not a compound, mixture or element.
It would be an alloy with some compounds (lead oxides) in a thin layer on its surface.
(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 mixture.
Lead weights are typically made of a mixture of lead metal and other elements such as antimony or tin to increase hardness. So, lead weights are considered a mixture of elements.
