Br- is chemical symbol for a bromide anion. It is not an 'equation', it can be a part of a chemical equation, like in this precipitation reaction (example)
Ag+(aq) + Br-(aq) --> AgBr(s) .
The chemical equation for the reaction between toluene and bromine (Br) is C6H5CH3 + Br2 → C6H5CH2Br + HBr. This reaction is an electrophilic aromatic substitution where one of the hydrogens on the benzene ring is replaced by a bromine atom.
The balanced chemical equation for potassium bromide is KBr(s) --> K+(aq) + Br-(aq).
Nothing happens:Br- + I- + HCl --> Br- + I- + H+ + Cl-
the chemical symbol is Br :)
The balanced chemical equation for cesium bromide is 2CsBr -> 2Cs + Br2.
Bromate is a polyatomic ion made of Bromine and oxygen: BrO3-
When hydrogen bromide reacts with water, it forms hydrobromic acid, which can be represented by the chemical equation HBr + H2O → H3O+ + Br-. This reaction involves the dissociation of hydrogen bromide into H+ and Br- ions in solution.
A chemical equation is a shorthand description of a chemical reaction.
A chemical reaction can be represented by a chemical equation.
The chemical symbol for bromide is Br^-. This notation indicates that the bromide ion has a charge of -1.
Bromine is an element, one of the halogens. Its chemical symbol is Br.
The balanced equation for the reaction of C6H5MgBr with ammonia (NH3) is: C6H5MgBr + 2NH3 -> C6H5NH2 + Mg(OH)Br
