Amanufacturer of trophies wants to cover a trophy made of tin with thin layers of silver and gold. which of the following processes should the manufacturer use to perform this task? a.) anodization b.) electroplating c.) electrometallurgy d.) hydrolysis

B.) electroplating

Explanation:

In the process of electroplating an expensive metal such as gold is coated over a base metal in thin layers in the presence of electricity. Electroplating takes place in an electrolytic cell, where the gold is the anode and the base metal is the cathode. A DC current is applied to complete the circuit. The gold ions are reduced and get deposited at the cathode.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
