If an atom gains an electron and gets a negative charge because of it, it is a negatively charge ion AKA an anion.
Answer:
B. Below the equilibrium price
Explanation:Price ceiling is the legal price,impose by The Government or Regulatory agencies above which a product should not be sold. It is also a price control mechanism through which the Government and other Regulatory agencies check the excesses of producers and the middle men(Whole sellers and retailers). The price ceiling has to be fixed below the equilibrium price for it to be binding, because businesses are interested mainly for profit maximization.
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.

Answer:
50. 5mol
Explanation:
The mass of Zinc required = 3.30 kg = 3300 grams
The relation between moles and mass is:

Atomic mass of Zinc = 65.38g/mol


The answer to three significant figures will be 50.5 mol
The answer for that kind of question depends on many things. location, how many people will inhabit the home, whether or not the home is a vacation home or a full time home. etc. P.S. I do not believe that this has anything to do with chemistry
