The balanced reaction that describes the reaction between hydrogen and chlorine to produce hydrogen chloride is expressed H2 + Cl2 = 2HCl. Hence for every mole hydrogen chloride produced, there is 1 mole of hydrogen and chlorine needed. When 1 mole each of the reactants are used, there is 72.9 grams of HCl produced. We multiply 2 with the molar mass of HCl.

<h2>COVALENT BOND</h2>

- What happens to the electrons in a completely covalent bond?

- <u>Covalent bonding</u> <u>occurs when atoms share electron pairs</u>. To increase their stability, atoms will form covalent bonds with other atoms, <u>which is accomplished by forming a full electron shell</u>. By sharing their outermost (valence) electrons, atoms can fill up their outer electron shells and gain stability.
