Is the following chemical equation balanced? MgI 2 + Br 2 MgBr 2 + I 2

count the elements in eqn MgI2 + Br2 - > MgBr2 + I2

1 Mg, 2I, 2Br on the left n

1 Mg, 2I, 2Br on the right

they are equal so the eqn is balanced

Both Br and I are part of the Halogen group. They have similar chemical properties. In this case, the chemical equation represents a displacement reaction in which the I in MgI2 is displaced by Br to form MgBr2:

MgI2 + Br2 = > MgBr2 + I2

The equation is valid and balanced.
