Why the molecular formula of calcium carbide is cac2 but not ca2c

The two carbons have a triple bond leaving two unpaired electrons which take the two calcium electrons to form the acetylide ion (C2–2) and the Ca+2 ion. The C-4 ion is not a stable species.

it should be all of them because it asks if you included all of those in your answer

explanation:

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
