Morgan and Jacob are conducting a chemical experiment involving sodium hydroxide. A key part of the reaction is ensuring that the sodium hydroxide is dissolved in water before adding the other materials. Morgan uses a pestle and mortar to crush the sodium hydroxide into a fine powder before adding it to his reaction mixture. Jacob doesn't feel like doing that because he is not very motivated, so he adds the sodium hydroxide in the form of large chunks. Who will be able to add the other materials to their reaction later?

Answer: Jacob
