Oxalic acid
Hydrogen has an oxidation number of +1
Oxygen's oxidation number is -2
carbon has an oxidation number of +3
H: 2 x (+1)=+2
O: 4 x (-2)= -8
C 2 x (+3)= +6
+2 + -8 + +6 = 0 (all compounds have a total charge of zero)
Oxalic acid monohydrate
h2c204+h2so4
Diprotic, hence polyprotic.We'll documented by NIH.The two reactive hydrogen are found bonded to C2 And C3 in the molecule. You can also check the molecular formulae for ascorbic acid and dehydroascorbic acid and note the loss of TWO hydrogen.

It's oxalic acid - imagine two carboxylic acid functional groups directly bound to one another. Check the link.
0.063 g of oxalic acid * (1 mol H2C204*2H2O / 126.07 g) = 0.0004997 mol H2C2O4*2H2O 0.0004997 mol H2C204 / 0.250 L = 0.001999 M of H2C2O4

Methane is a compound because it consists of two elements chemically bonded together and has its own unique properties.
