Question

find the compound of copper oxide in Criss cross method​

Answer 1

Answer:

Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxidesof copper, the other being Cu2O or cuprous oxide. As a mineral, it is known as tenorite. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds.

Answer:

• Answer:The Thorpe's Crisscross method is a method of finding out the chemical formula of a metal and non-metal that combine to form an ionic bond created by high school chemistry teacher Kim Thorpe.[1]

• Answer:The Thorpe's Crisscross method is a method of finding out the chemical formula of a metal and non-metal that combine to form an ionic bond created by high school chemistry teacher Kim Thorpe.[1]To use this method, the absolute value of the oxidation number of the first ion is used as the subscript of the second, and vice versa. The subscripts are then reduced by the greatest common factor. For instance, to find the formula for aluminium oxide:
