Two covalent bonds attach both Oxygen atoms to the Carbon atom. You should have figured that out using the Lewis structure.
A Lewis structure is a model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs this is a CO32− model
The substance not paired correctly isCl2 - polar covalent bonds.
Lewis dot structures are used to represent the covalent electrons of an element. It can be used to show the sharing of covalent electrons in a covalent bond or just to show the covalent bonds in general.
The bonds are covalent.
The Lewis dot structure for hydrogen bromide (HBr) consists of a single covalent bond between the hydrogen atom and the bromine atom. So, there is one single covalent bond in the Lewis dot structure of HBr.

The cells in hair are held together by covalent bonds and covalent bonds are affected by water.
CO2 molecule has two double bonds.
Lewis structure
MOLECULE
it is a molecule
Covalent bonds are the easiest to break, since they are the easiest to make. But no substance is made when bonds break.
