Which is an example of a polyatomic ion?

h2
co3-
mg+
ne+ -

Answer;

CO3-

Explanation;

Polyatomic ions are covalently bonded groups of atoms with a positive or negative charge caused by the formation of an ionic bond with another ion. Compounds formed from such ion combinations are called polyatomic ionic compounds, but the polyatomic ion behaves as a single unit.

Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, CO3-, contains one carbon atom and three oxygen atoms.

CO3-

I took the quiz and got 100 on EDGE

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
