How do you write the oxidation number of the element in the compound KBr?
The oxidation number of K (Potassium) in KBr (Potassium Bromide) is +1. This is because alkali metals like Potassium typically have an oxidation number of +1 in compounds.
What is the oxidation number of bromine in KBr?
The oxidation number of bromine in KBr is -1. In ionic compounds, the oxidation number of the cation (K+) is always equal to its charge, which is +1. Therefore, the oxidation number of bromine must be -1 to balance the overall charge of the compound.
How many moles of kbr are present in 25ml of a 1.5 M solution?
To find the number of moles of KBr in the solution, first calculate the number of moles of KBr in the 25 mL solution using the given concentration and volume. $$moles = concentration \times volume$$ Then, multiply the moles by the molecular weight of KBr to get the mass of KBr in the solution if needed.
How many moles are contained in 22.23 g KBr?
To find the number of moles in 22.23 g of KBr, we need to divide the given mass by the molar mass of KBr. The molar mass of KBr is 119 g/mol. Therefore, 22.23 g of KBr is equal to 0.187 moles.
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 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 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 sand?
Silicon's oxidation number is +4.Oxygen's oxidation number is -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?
The oxidation number for Nb in NbO2 is +4. Oxygen has an oxidation number of -2, so the overall charge of the compound must be balanced by the oxidation number of niobium.
Rank these items in order of increasing oxidation number for manganese MnCl2 Mn KMnO4 Mno2 lowest oxidation number?
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
What is the oxidation number of H2O2?
The oxidation number for H is +1, and the oxidation number for O is -1.
