Determine the number of ions produced in the dissociation of the compound listed. CaO

There are 2 ions.

Explanation:

In CaO, there is calcium ion and oxygen ion.

Calcium loses electrons into positively ion and oxygen loses electrons into negatively ion.

(Correct me if I am wrong)

2 ions are prouced in the dissaciotion of the compound

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
