    1. acidity

      In this table I counted 14 missing bonds that should be drawn in... I'm starting to question if this is on purpose or not and if it is I am so confused as to why.

    1. pKapKapK_a

      There are 2 bonds that are missing from the drawing of the aromatic compound below. There is an NH2 and H seemingly floating in space

    2. water

      There is no bond between the third H and the O in the hydronium Ion

    1. carbonyl

      The carbonyl oxygen has a single bond in the reactants and a double bond in the products. However in the reactants it has only 2 lone pairs, the amount necessary for a 0 formal charge when oxygen has a double bond and no formal charge is present in the reactants.

    2. The conjugate base of the acetate ion is missing the double bond of the oxygen in the products side of the reaction. The bond that is there was not drawn centered so the line is clearly missing.

    3. acid

      The picture of the OH + HCl reaction has a mistake, on the product side, the conjugate acid of OH, H2O does not have bonds drawn to both hydrogens, only to one of them. Yet the oxygen has only 2 lone pairs implying that it should have 2 bonds. I would have clicked on the picture but it would not let me.

    1. sucrose

      This question is not entirely true, sugar especially like salt can't actually sit for years, maybe 3-6 months if you're lucky and don't like to bake a whole lot. If sugar sits, it's a humectant so it draws in the moisture in the air and creates large clumps that become rocks and are unusable. The question is simply false.
