Balancing Chemical Equations

Challenge: Who can balance the MOST Chemical Equations? Click on the blue dots to enter the coefficient(s) that balances this equation. All blue dots must have a number for the question to be considered complete. Even if the number is 1 and we don't usually write the 1, write the 1 for this wizer to grade it correctly. 4 1 2 Click on the blue dots to enter the coefficient(s) that balances this equation.
