Answer
The second part of the theory says all atoms of a given element are identical in mass and properties. The third part says compounds are combinations of two or more different types of atoms. The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.

Answer:
# 5
Explanation:
The question describes silver being "poured" into a mold and cools to become a solid bar. This is the phase of liquid to solid. When a element cools down below it's freezing points to become a solid.
<u>Liquid to Solid Definition:</u>
Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point. All known liquids, except helium, freeze when the temperature is low enough.
The kind of chemical catalysis is covalent catalysis and among the given amino acids lysine will act as a catalyst for the reaction.
The generation of iminium ions in the transition state of the reaction confirms that it is a covalent catalysis. lysine is the only amino acid that can catalyze the iminium ion generated in the transition state of the reaction.
So the answer for the type of catalysis is covalent catalysis, and the answer for the type of amino acid among the given amino acids that can catalyze the reaction is lysine.
