To determine the oxidation number for Co in CoCl3, we need to consider that the overall charge of CoCl3 is 0 and Cl has an oxidation number of -1. By setting up an equation (x + 3(-1) = 0) where x is the oxidation number for Co, we find that Co has an oxidation number of +3 in CoCl3.

What is the oxidation number for MO?
The oxidation number for the compound MO can vary depending on M. In general, oxygen has an oxidation number of -2. Therefore, you would need to know what element M represents in order to determine the oxidation number for MO.
If an element gains electrons what type of oxidation number does it have and how do you know?
If an element gains electrons, it has a negative oxidation number. The oxidation number is determined based on the number of electrons gained or lost by an atom in a compound. The rule is that in ionic compounds, the oxidation number of an element is equal to the charge it would have if it were an ion.
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.
How do you prove the oxidation number of P is -3?
To prove the oxidation number of phosphorus (P) is -3, you can consider the compound PH3, where hydrogen is always assigned an oxidation number of +1. Since PH3 is a neutral molecule, the oxidation numbers must add up to zero. Therefore, the oxidation number of P in PH3 must be -3 to balance out the +1 oxidation number of each hydrogen atom.
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 molar mass of CoCl3?
You can use an online tool to calculate the molar mass of CoCl3 - convertunits.com/molarmass/CoCl3
Why do you need to know the oxidation number of the elements?
because if you know the oxidation numbers of all the reactants and products in a given reaction, you can determine which, if any, of the reactants were oxidized and which were reduced. oxidized is when the oxidation number increases, reduced is when the oxidation number decreases.
What is the formula for cobalt(III) chloride?

How do you know the oxidation number in an formule with more then 2 unknowns for example OCN- you only know O is -2?
It is not possible to know the oxidation number in an formula with more then 2 unknowns such as OCN- you only know O is -2.
What is the oxidation number of IF?
The oxidation number of iodine in IF is +1 because fluorine is more electronegative than iodine and will take on a charge of -1. Since the compound is neutral, the oxidation number of iodine must be +1 to balance the -1 charge of fluorine.
What is the correct name for compound cocl3?
The correct name for the compound CoCl3 is cobalt III chloride.
What is the oxidation number of HClO?
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
What is the oxidation number of zns?
The oxidation number of ZnS (zinc sulfide) is 0. Zinc (Zn) typically has an oxidation number of +2, while sulfur (S) typically has an oxidation number of -2. In a compound like ZnS where there is no charge indicated for the compound, the total oxidation number must add up to 0.
What is the Oxidation number of sand?
Silicon's oxidation number is +4.Oxygen's oxidation number is -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 for k2cro4?
In K₂CrO₄, the oxidation number of potassium (K) is +1, and the oxidation number of oxygen (O) is -2. Since the compound is neutral, the oxidation number of chromium (Cr) can be calculated as follows: 2(+1) + Cr + 4(-2) = 0. Solving for chromium, the oxidation number of chromium in K₂CrO₄ is +6.
