Give the systematic names for the formulas, or the formulas for the names. (Type your answer using the format copper(II) chloride for CuCl2, and using the format CO2 for CO2. Omit the centered dot for hydrates.)
A carboxylic acid favours the ion form (R-COO-) and its pH is higher than its pKa. In most membranes, the polar heads of the phospholipids align towards the middle of the membrane.
