Explain whether co2 (o = c = o) is an ionic or a covalent compound. why does this arrangement satisfy all atoms involved?

Carbon dioxide (CO2) is a covalent compound because it is composed of carbon and oxygen. Herein both the elements i.e. C and O are non-metals.

These elements share the electrons. When electrons are shared, each atom will contain 8 electrons in the outer shell. Due to this, all the atoms of the CO2 will become stable and they will have a completed outer shell.

The lewis structure of CO2 is shown below:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
