This is a CLOSED COMPUTER assignment. DO NOT rewrite the equations! Add the numbers needed to balance these equations. If the products are not given, write the correct product formulas, then balance the equation. If a name is given, write the correct chemical formula in the blank, then balance the equation.

You are expected to complete this assignment during class today. Your science facilitator is available for individual help − but not your neighbor.

Do not leave class today without a complete understanding of this concept. Your success during the rest of the year depends on it!
