Answer : The given equation are not balanced equation.
Explanation :
Balanced chemical equation : It is defined as the number of atoms of individual elements present on the reactant side must be equal to the number of atoms of individual elements present on the product side.
The given chemical reaction is,
This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of oxygen are not balanced and the molecule 
are missing on the product side.
So, in order to balanced the chemical reaction, the molecule are added on the product side.
Thus, the balanced chemical reaction will be,
When an atom loses a electron it becomes a positive ion.
<span>The substance that is produced at the cathode during the electrolysis of a mixture of molten calcium bromide, cabr2(I), and molten magnesium iodide, mgi2(I), can be expressed as Ca2+ + 2eâ’ --> Ca. At the anode, the substance can be expressed as 2Brâ’ â’ 2eâ’ --> Br2. At the cathode for magnesium iodide can be expressed as Mg2+ + 2 eâ’ --> Mg, and 2 Iâ’ â’ 2 eâ’ --> I2 at the anode.</span>
That would be the proton. The number of protons in the nucleus determine which element it is and its properties.
