You have seven closed containers, each with equal masses of chlorine gas (Cl 2 ) . You add 10.0 g of sodium to the first sample, 20.0 g of sodium to the second sample, and so on (adding 70.0 g of sodium to the seventh sample). Sodium and chlorine react to form sodium chloride according to the equation 2 Na ( s ) + Cl 2 → 2 NaCl ( s ) After each reaction is complete, you collect and measure the amount of sodium chloride formed. A graph of your results is shown below. Answer the following questions: a. Explain the shape of the graph. b. Calculate the mass of NaCl formed when 20.0 g of sodium is used. c. Calculate the mass of Cl 2 in each container. d. Calculate the mass of NaCl formed when 50.0 g of sodium is used. e. Identify the leftover reactant, and determine its mass for parts b and d above.

Interpretation: Seven closed containers, having equal amount of chlorine gas present in them, have been given. Sodium is added to the containers in the given pattern. After the completion of the reaction between sodium and chlorine, the amount of sodium chloride formed is measured. The stated questions related to the given process are to be answered.

Concept introduction: The amount of the sodium chloride formed depends upon the amount of sodium and chlorine gas present in each of the given containers.

To determine: The explanation regarding the shape of the graph.

The amount of sodium chloride formed increases on increasing the quantity of sodium from the container one to four.

In the fifth container the addition of a greater amount of sodium than added to the previous container did not increase the amount of sodium chloride formed...
