To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.Given equation: CF4 + Br2 → CBr4 + F2Step 1: Count the number of atoms of each element on both sides of the equation.On the left side:- C: 1- F: 4- Br: 2On the right side:- C: 1- Br: 4- F: 2Step 2: Balance the atoms of each element by adjusting the coefficients.To balance the carbon atoms, we need to have 1 CF4 molecule on the left side.To balance the bromine atoms, we need to have 2 Br2 molecules on the left side.To balance the fluorine atoms, we need to have 2 F2 molecules on the right side.Balanced equation: CF4 + 2 Br2 → CBr4 + 2 F2Therefore, the correct answer is 1, 2, 2, 1.
