After the reaction mixture is added to the top of the silica gel column, the instructions state: "Open the stopcock and drain the column until the meniscus is just above the top layer of the material. Add another 0.5 mL of solvent and repeat the process toensure that all of the desired products are adsorbed onto the silica gel. This process ensures that none of the desired products are dissolved in solution above the column."Why is this procedure important? How would the TLC plates look different than your prediction in Q1 if a student skipped this step?

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
