No, the reaction 2K + Br2 is not balanced. To balance it, you would need to change the coefficients of the reactants and products so that the same number of each type of atom is present on both sides of the reaction arrow.
The reaction 2KBr → 2K + Br2 is endothermic because heat must be supplied to break the bonds in potassium bromide (KBr) in order to form potassium (K) and bromine gas (Br2).
The balanced equation for the reaction between zinc (Zn) and bromine (Br2) is: Zn + Br2 -> ZnBr2.
The reaction between Mg and Br2 results in the formation of MgBr2. The balanced chemical equation is: Mg + Br2 → MgBr2
The chemical reaction between 2 mol of Cl2 and Br2 forms 2 mol of ClBr3, a molecule known as chlorine bromide. The balanced chemical equation for this reaction is: 2 Cl2 + Br2 → 2 ClBr3.
C8H16 + Br2 -> C8H16Br2
The equation 2K + Br2 -> 2KBr is balanced as there are equal numbers of atoms of each element on both sides of the reaction.
The reaction 2KBr → 2K + Br2 is endothermic because heat must be supplied to break the bonds in potassium bromide (KBr) in order to form potassium (K) and bromine gas (Br2).
KCl: 2K(s) + Cl2(g) -> 2KCl(s) Br2: Br2(l) -> 2Br(s)
The balanced equation for the reaction between zinc (Zn) and bromine (Br2) is: Zn + Br2 -> ZnBr2.
The chemical reaction is:C2H2 + Br2 = CHBr=CHBr
The reaction between Mg and Br2 results in the formation of MgBr2. The balanced chemical equation is: Mg + Br2 → MgBr2
You need to have values for K, Br2 and 2KBr in order to find out the balance. For example, if you had the values as H2 + O2 = H20 the balanced chemical equation would be 10 H2 = H20.
The balanced chemical equation for the reaction between chlorine (Cl2) and bromine (Br2) is: Cl2 + Br2 -> 2ClBr
Br2 + 3NaHSO3 = 2NaBr + NaHSO4 + H2O + 2SO2
The redox reaction you provided is unbalanced. The correct balanced redox reaction should be 2Cl + Br2 -> 2Cl- + 2Br. This balanced equation ensures that both charge and mass are conserved during the reaction.
