the oxidation number is 0
consider two moles of HCHO as 2HCHO = 2CO & H2 here O has oxidation no = -2 & so C shall have oxidation no = +2
The oxidation state of carbon in formaldehyde (CH2O) is +2. This is because oxygen typically has an oxidation state of -2, and there are only two atoms of oxygen present in formaldehyde. The overall charge of formaldehyde is zero, so the sum of the oxidation states must equal zero, leading to carbon having an oxidation state of +2.
H is +1, O is -2 overall carbon will have an oxidation # of -3
The oxidation number of C in C₂O₄ is +3. Each oxygen atom carries a charge of -2, and since there are 4 oxygen atoms in total with a total charge of -8, the carbon atom's oxidation number must be +3 to balance the charges in the compound.
The oxidation number for carbon (C) in carbon dioxide (CO2) is +4. Each oxygen atom has an oxidation number of -2, so in the compound CO2, the total oxidation number must equal 0.

The oxidation number for carbon (C) in carbon dioxide (CO2) is +4. Each oxygen atom has an oxidation number of -2, so in the compound CO2, the total oxidation number must equal 0.
The oxidation number is + for C and -2 for O.
The oxidation number of C in CO3^2- is +4. Each oxygen atom has an oxidation number of -2, and since the overall charge of the carbonate ion is 2-, the carbon atom must have an oxidation number of +4 to balance the charge.
+2 for Mg +4 for C -2 for each O
It depends on what form it is in. It can be in the 4+ oxidation state, 4- oxidation state and every oxidation state in between.
The oxidation number of Ca is 0 in its elemental form and is +2 in its compounds.
To find the number of molecules in 30.0 g of CH2O, you first need to calculate the number of moles of CH2O using its molar mass (12.01 g/mol for C, 1.01 g/mol for H, and 16.00 g/mol for O), and then use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
CO is a harmful gas.C shows +2 in CO and it shows +4 in CO2.
