## Step 1The given equation is . This equation represents a chemical reaction where nitrogen (N2) and fluorine (F2) combine to form nitrogen trifluoride (NF3).## Step 2To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. This is in line with the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.## Step 3Looking at the equation, we can see that there are 2 nitrogen atoms on the left side (in ) and 1 nitrogen atom on the right side (in ). Similarly, there are 2 fluorine atoms on the left side (in ) and 3 fluorine atoms on the right side (in ).## Step 4To balance the nitrogen atoms, we need to multiply by 2, giving us 2 nitrogen atoms on both sides. This changes the equation to .## Step 5Now, we have 2 nitrogen atoms on both sides, but we have 6 fluorine atoms on the right side (in ) and only 2 fluorine atoms on the left side (in ). To balance the fluorine atoms, we need to multiply by 3, giving us 6 fluorine atoms on both sides. This changes the equation to .## Step 6Now, the equation is balanced with 2 nitrogen atoms and 6 fluorine atoms on both sides. Therefore, the coefficients for the equation to be properly balanced are 1, 3, and 2.
