Yes, the equation K + Br2 = KBr is a balanced chemical equation. For example, 2 K + Br2 = 2 KBr is one and another balance chemical equation is Fe + Cl2 = FeCl3.
2KBr + Cl2 ----> 2KCl + Br2
2KCl + Br2 ---> Cl2 + 2KBr
This is a halogen single replacement reaction, in which the more active chlorine will take the place of the bromine in the potassium bromide. 2KBr + Cl2 --> 2KCl + Br2
2KBr + 2H2O----->2KOH + Br2 + H2(g) this is the reaction in electrolysis of KBr in aqueous solution
2KI+Br2 ---->2KBr +I2
No. No. No. No.
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.
2KBr + Cl2 ----> 2KCl + Br2
Br2 + 2KI -> 2KBr +I2
Balanced:2 K + Br2 ----> 2 KBr
it is unanswered
2K2MnO4 + Br2 ----> 2KMnO4 + 2KBr
2KCl + Br2 ---> Cl2 + 2KBr
This is a halogen single replacement reaction, in which the more active chlorine will take the place of the bromine in the potassium bromide. 2KBr + Cl2 --> 2KCl + Br2
2KBr + 2H2O----->2KOH + Br2 + H2(g) this is the reaction in electrolysis of KBr in aqueous solution
