Scenario: Professor Snape needs to have his students make a potion that contains five specific ingredients. Hogwarts supply manager bought the ingredients, but unfortunately they were all mixed together in the wrong proportions for the potion to work. Professor Snape assigned Professor Assistant (PA) Reeves to separate the five ingredients from the mixture. As a student of PA Reeves your role is to come up with a set of procedures that will separate the five ingredients from the mixture that Hogwarts supplier purchased. (Magic does not work at this point) The mixture contains, sand, water, iron, salt, and rocks. Write out the procedure in the box below.

explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
