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 + F2Let's balance the equation step by step:1. Balance the carbon atoms: - There is 1 carbon atom on both sides of the equation, so the carbon atoms are already balanced.2. Balance the fluorine atoms: - There are 4 fluorine atoms on the left side (in CF4) and 2 fluorine atoms on the right side (in F2). - To balance the fluorine atoms, we need to multiply the F2 molecule by 2.3. Balance the bromine atoms: - There are 2 bromine atoms on the left side (in Br2) and 4 bromine atoms on the right side (in CBr4). - To balance the bromine atoms, we need to multiply the Br2 molecule by 2.The balanced equation is:CF4 + 2Br2 → CBr4 + 2F2Therefore, the correct answer is 1, 2, 1, 2.
