Answer:
Sandmeyer Reaction
Explanation:
When benzene diazonium chloride is treated with cuprous chloride in HCl, chlorobenzene is formed.
This reaction is called Sandmeyer reaction. In this reaction, the diazonium group is replaced by chloro group.
Sandmeyer reaction is used to replace the diazonium group with chlorine, bromine or cyano group.
Final amount =initial anount *(1/2)^(t/half life)
final amount =2.000 mg *(1/2)^(10.5/5.20) = 0.493 mg remain after 10.5 years
PH= pKa + log( conjugate base/ conjugate acid)
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to figure out the required net ionic equation by firstly writing out the complete molecular equation between aspirin and sodium acetate:
Whereas acetic acid and sodium acetylsalicylate are formed. Now, we write the complete ionic equation whereby sodium acetate and sodium acetylsalicylate are ionized because they are salts yet neither aspirin nor acetic acid are ionized as they are weak acids:
Finally, for the net ionic equation we cancel out the sodium spectator ions to obtain:
