The molecular formula out of the options provided is CO, which represents a carbon atom and an oxygen atom bonded together. The other options, Co and C2O4, do not represent a molecular formula but instead may refer to cobalt (Co) and oxalate ion (C2O4^2-), respectively.
A reaction is:FeCl3·6H2O + 3 K2C2O4•H2O = K3[Fe(C2O4)3]·3H2O + 3 KCl + 6 H2O
Formula: Gd2(C2O4)3
The free energy for the C2O4-2 ion can vary depending on the specific conditions such as temperature and pressure. To calculate the free energy for C2O4-2, you would typically need to know the free energy of formation for the ion under standard conditions and apply appropriate corrections based on the specific conditions of interest.
I'm not sure, but my guess is: W(C2O4)5(HO4)4 Since Tungsten symbol is W and has a variable charge of 5. Oxylate is C2O4 and will put the variable charge of tungsten after the parenthesis of oxylate (C2O4)5. And since, "hydrate" symbol is HO4 and has a prefix of "tetra", it will now written as (HO4)4 Formula: W(C2O4)5 (HO4)4 Feel free to correct my answer co'z I'm not sure.
C2O4 has a charge of -2
The symbol for oxalate ion is C2O4^2-.
Th (C2O4)2.6H2O or Th (C2O4)2.2H2O
The chemical name for C2O4 with a charge of -2 is Oxalate.
The molecular formula out of the options provided is CO, which represents a carbon atom and an oxygen atom bonded together. The other options, Co and C2O4, do not represent a molecular formula but instead may refer to cobalt (Co) and oxalate ion (C2O4^2-), respectively.
The chemical formula of sodium oxalate is Na2C2O4.
Calcium, strontium and Barium form white precipitates of their oxalates with C2O4-2 ions.
Formula: C2O4-2
The chemical formula for ferric ammonium oxalate is (NH4)3Fe(C2O4)3.
Oxalic acid.
A reaction is:FeCl3·6H2O + 3 K2C2O4•H2O = K3[Fe(C2O4)3]·3H2O + 3 KCl + 6 H2O
The chemical formula for nickel(III) oxalate is Ni2(C2O4)3.
