How many moles of NaOH are required to make 500 mL of a 0.300 M solution?
Chlorine gas can be produced commercially by passing an electric current through a con- centrated solution of sodium chloride (brine).
Going off of what our teacher was saying about the concept that a system's attempt to establish equillibrium is the true driving force of all chemical processes.
Problem- Draw the mechanism (using curly arrows) for the Electrophilic Aromatic Substitution of anisole in the Para position by the nitronium ion. Include two steps: the formation of the sigma complex, then all the products.
