Which of the following is a covalent compound?

copper (sulfate), water, copper, magnesium oxide

Water is a covalent compound.

Explanation:

covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.

Example:

Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).

Properties:

1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.

2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

3. Covalent compounds have lower melting and boiling points.

this protocol provides a detailed procedure for total protein extraction for western blot analysis from achieved samples following trizol isolation of rna.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
