1.Chlorobenzene, C6H5Cl, is used in the production of chemicals such as aspirin and dyes. One way that chlorobenzene is prepared is by reacting benzene, C6H6, with chlorine gas according to the following BALANCED equation.
C6H6 (l) + Cl2 (g)  C6H5Cl (s) + HCl (g)a.
What is the theoretical yield if 45.6 g of benzene react?

Answer:

[tex]m_{C_6H_5Cl}=65.7gC_6H_5Cl[/tex]

Explanation:

Hello!

In this case, according to the given balanced chemical reaction:

[tex]C_6H_6 (l) + Cl_2 (g) \rightarrow C_6H_5Cl (s) + HCl (g)[/tex]

We can see there is 1:1 between benzene and chlorobenzene as the relavant product; thus, since the molar mass of benzene is 78.11 g/mol and that of chlorobenzene is 112.55 g/mol, the theoretical yield for this reaction turns out:

[tex]m_{C_6H_5Cl}=45.6gC_6H_6*\frac{1molC_6H_6}{78.11gC_6H_6 }*\frac{1molC_6H_5Cl}{1molC_6H_6}*\frac{112.55gC_6H_5Cl}{1molC_6H_5Cl} \\\\m_{C_6H_5Cl}=65.7gC_6H_5Cl[/tex]

Best regards!
