a teacher assigns the following experiment to a class. draw an outline of a birds feather, and color one - half of the outline with a thick coat from a wax crayon. leave the other half uncolored. next, sprinkle a few drops of water on both halves of the feather. you will observe that the water soaks into the plain paper. the waxy coat, however, allows the paper to remain dry. water forms tiny beads on top of the wax, instead of soaking through it. the diagram shows several water molecules in a water droplet. how does the structure of the water molecule help explain the ability of water to form beads on the wax?

Answer

Brief Explanations:

Water is a polar molecule with a bent shape. The oxygen - end is slightly negative and the hydrogen - end is slightly positive. Wax is non - polar. Due to the principle of "like dissolves like", polar water molecules are more attracted to each other (cohesion) than to the non - polar wax, causing water to form beads.

Answer:

Water is polar and wax is non - polar. Water molecules have strong cohesion due to their polarity, causing them to form beads on the non - polar wax surface instead of spreading out.
