Unlike what Jack has written in his table, the sun is comprised of 92% gas and has no definable rocky layer or even dust. The moon revolves specifically around the Earth.
The chemical formula of oxalic is 
When oxalic acid reacts with water, first, oxalic acid removes one proton and results in the formation of mono acids.
After that, in second step, oxalic acid in aqueous solution removes another proton which shows it is a polyprotic acid.
The chemical equations are: (the reactions occurs in two steps due to presence to hydrogen atoms).
When one proton is removed:
When another proton is removed:
The dissociation of oxalic acid in water in shown in the image.
Over land or over cooler water they start to lose their power
Graphite is a not metal because of the lack of the properties
- Metals are ductile but graphite is not ductile
- Metals are meleable but graphite is not meleable
- metal are sonorous but. graphite is not sonorous
- Metal are lustrous but graphite is not lustrous
Graphite contains only one property of metal
- metal is a good conductor of electricity but its a exception.
Because of all that reasons graphite is not included in metalloid.
Hope it helps u mate
