Chapter 9, Problem 18ALQ

You have seven closed containers each with equal masses of chlorine gas $\left({\text{Cl}}_2\right)$. 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 chloride react to form sodium chloride according to the equation

:math> 2 Na ( s ) + Cl 2 ( g ) → 2 NaCl ( s )

ter each reaction is complete, you collect and measure the amount of sodium chloride formed. A graph of your results is shown below.

swer the following questions:

l type='a'>

Explain the shape of the graph.

lculate the mass of $\text{NaCl}$formed when 20.0 g of sodium is used.Calculate the mass of ${\text{Cl}}_2$

, in each container.

lculate the mass of $\text{NaCl}$formed when 50.0 g of sodium is used.

Identify the leftover reactant and determine its mass for parts b and d above.
