What is the name of CuO? Explain how you determined the bond type and the steps you used to determine the naming convention for the compound.

Copper (II) oxide.

Explanation:

Hello!

In this case, since the nomenclature of chemical compounds depends on the nature of the compound and the elements forming it, due to the fact it has copper and oxygen, we infer it is a copper oxide. However, since the naming rules of oxides demand us to know the oxidation state of the metal, since oxygen is working with -2 and the both of them have 1 as their subscript, we infer that the copper works with +2 in order to achieve the charge balance equal to 0; therefore, the name of CuO would be copper (II) oxide.

The steps may be:

1. Identify the elements forming the compound.

2. Assign the oxidation state for each element.

3. Name the cation followed by the oxidation state into rounded brackets.

Best regards!

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
