The name of 2KBr is potassium bromide. It consists of two potassium (K) ions and two bromide (Br) ions, reflecting its chemical formula of KBr. Potassium bromide is commonly used in various applications, including pharmaceuticals and Photography.
No. No. No. No.
2KBr + Cl2 ----> 2KCl + Br2
The equation 2K + Br2 -> 2KBr is balanced as there are equal numbers of atoms of each element on both sides of the reaction.
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 equation for the reaction between bromine and potassium chloride is: 2KCl + Br2 -> 2KBr + Cl2
2K2MnO4 + Br2 ----> 2KMnO4 + 2KBr
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 is: Br2 + 2Kl -> 2KBr + I2. This means there is a 2 in front of the underlined substance, KI.
Balanced equation formed: H2SO4 + 2KBr ==> 2HBr + K2SO4
The reaction of potassium bromide with chlorine is known as a displacement reaction, where the more reactive chlorine displaces the less reactive bromide to form potassium chloride and elemental bromine.
Its actually: 2KI(aq)+Br2(aq)-> I2(s)+2KBr(aq)
1 (fully) and 4 (only partial) are decomposition reactions.
