These proteins are called List 3 examples of ionic compounds: List 3 examples covalent molecules: 10. Below are listed two water molecules. Label ALL of the following in the diagram: hydrogen atom, oxygen atom, covalent bond, hydrogen bond, partial positive charge, partial negative charge.

Answer 1

- → stoms having a positive charge and negative charge are held together by ionic interactions. Two charged atoms held together by ionic bond forms a new chendical and is reffered to as an ionic compound. Ionic bonds may be easily broken using polar solvents. Eg 1) Nace - Nat ce- (Sodium chloride) 3) My ly a ma* ace" (Magnesium chloride) 3) (NH4) SA 3 Nhur sot (Ammonien prate)

- Atoms held together by covalent bonds must share equal electrons in their halence shell Two atoms held together by a covalent bond from a new Chemical and is referred to as a covalent compound covalent bonds may be broken by extreme heating under acidic conditions, or by using proteins that catalyze hydrolysis of the covalent bond- These proteins are called peptidase (been breaks keptide bonds.). ® CHA H C H Methane & N=0 NO > Nitrogen monooxide ② No Nitrogen dioxide INTO
