What is the oxidation number of Fe and Cr in FeCr2O7?

The possible oxidation numbers for iron cations are +2 and +3. Oxygen in oxyanions is usually assigned an oxidation number of -2, producing a total negative charge of -14 for the seven oxygen atoms in a dichromate anion. If the iron cation has an oxidation number of +2, the two chromium atoms must have a total oxidation number of +12, which is possible when each chromium atom has an oxidation number of +6. An iron (III) cation would require the chromium atoms to have a non integral charge, which is not possible since electrons with half charges are not known. Therefore, the oxidation number of iron in the compound is +2 and the oxidation number for chromium is +6.


What is the oxidation number of acetate?

The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.


What is the oxidation number of H2CO2?

The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.


What is the oxidation number of nitrosyl?

The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.


What is the oxidation number for Nb in NbO2?

Oxidation number of Nb is +4. Oxidation number of O is -2.

If 309 moles of FeCr2O7 react how many moles of O2 will be consumed?

To determine how many moles of O2 are consumed when 309 moles of FeCr2O7 react, we first need the balanced chemical equation for the reaction. Assuming FeCr2O7 decomposes to yield Fe, Cr, and O2, a typical reaction could produce 3 moles of O2 for every mole of FeCr2O7. If this is the case, 309 moles of FeCr2O7 would consume 3 × 309 = 927 moles of O2.
