How many valence electrons are there for the POCl3 molecule? Draw a reasonable Lewis structure for POCl3. Assign formal charges for the atoms in your Lewis structure. Draw a second legitimate resonance contributor for POCl3. Assign formal charges for your second resonance contributor.
Suppose that a fully charged lead-acid battery contains 1.50L of 5.00M H2SO4. What will be the concentration of H2SO4 in the battery after 3.40A of current is drawn from the battery for 4.50 hours?
To construct a detailed sequence of reactions to synthesize 4-cyclohexyl-3-methyl-1-butanol as the MAJOR substrate product.
A solution is created by adding 0.05 moles of H2CO3 (3.1 g, total mass) to 5-L of water, resulting in a pH of 4.2. What is the alkalinity of this water (in meq/L)? Does the answer make sense, why or why not
