Answer:
H2 + I2 —> 2HI
Explanation:
H2 + I2 —> HI
Now, let us balance the equation. This can be achieved by doing the following:
There are 2 atoms of H on the left side of the equation and 1atom on the right side. It can be balance by putting 2 in front of HI as shown below:
H2 + I2 —> 2HI
Now the equation is balanced as there are equal numbers of atoms of the different elements present on both sides of the equation.
