When an atom undergoes oxidation what happens to the number of neutrons?
Oxidation is a chemial reaction; the atom and the number of neutrons remains unchanged.
Is the molecule HOBr polar?
Yes, the molecule HOBr is polar. This is because the molecular geometry of HOBr is non-symmetrical, leading to an uneven distribution of charge within the molecule, causing it to be polar.
Chemical Reaction between bromine and water?
When bromine reacts with water, it forms hydrobromic acid (HBr) and hypobromous acid (HOBr). The overall reaction can be represented as: Br2 + H2O → HBr + HOBr. This reaction is reversible and depends on the pH and conditions of the solution.
Where did francium get its symbol?
The chemial symbol Fr is derived from the first two letters of the name Francium.
Is HOBr polar or non-polar?
HOBr is a polar molecule. This is because it has a bent molecular geometry, with oxygen pulling electrons more strongly than bromine, leading to an uneven distribution of charge within the molecule.
What is bromine reaction with water?
Bromine reacts with water to form a mixture of Hydrobromic Acid, HBr, and Hypobromous Acid, HBrO.
What is the oxidation number of bromine in HOBr?
The oxidation number of bromine in HOBr is +1. This is because the oxidation number of oxygen is typically -2 and the overall compound is neutral, so the oxidation number of hydrogen is +1. This leaves bromine with an oxidation number of +1 to balance the compound.
What is another name for chemial change?
Another name for a chemical change is a chemical reaction. It is a process where one or more substances are converted into different substances with unique chemical properties.
