Copper sulfide is found written as both CuS and Cu2S. Why are there two forms for writing this chemical formula? SELECT AN ANSWER

This is an example of a combination reaction: CuS is the halfway stage, before the second copped atom joins the molecule.

Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).

This is a synthesis reaction and so the formula will continue changing until all the atoms have conglomerated.

One of the versions is a mistake, the correct form should be Cu2S.

Agenetically engineered corn plant is approved for agricultural use. the plant produces pollen that can make its own toxins. these toxins protect the corn plant against pests and no longer require the application of chemical pesticide. what is a likely impact on the farmer of growing such a variety of corn? a- the financial costs for the farmer would be lowered since less crops would be lost to pests. b-the financial costs for the farmer would be lowered since more crops would be lost to pests. c-the farmer may be held responsible for increasing chemical pollution. d-the farmer's expenses for pest control would increase due to an increase in bee population.
