Question 1 (2 points) What is the purpose of balancing chemical reactions? 0 To increase the amount of product produced. C) To obey the law of conservation of mass. (J To show that Newton's iaws are true. C) To show that energy is not created or destroyed. Question 2 (2 points) What does the law of conservation of mass state? 0 Energy cannot be created or destroyed. O The total mass of reactants in a reaction must e qua! the totai| mass of the products. 0 The total mass of the products in a reaction is mo re than the total mass of the reactants. Question 3 (2 points) U change subscripts Add subscripts to chemical formulas Question 4 (2 points) What change could you make to properly balance the chemical equation? Na + Cl2 -> 2 NaCI Add a coefficient of 2 in front of Na Remove the 2 from in front of NaCl Add a subscript of 2 to Na Remove the subscript from CI Question 5 (2 points) What change could you make to properly balance the chemical equation? H2 + 02 -+ 2H 20 Remove the 2 from in front of H20 O Add a coefficient of 2 in front of H2 Change the subscript on H from 2 to 4 Add a subscript of 2 to Na
