Awater molecule is composed of a large oxygen atom bonded to two small hydrogen atoms. which of the following would make the best model of a water molecule?

a. a drawstring bag filled with blue, green, red, and yellow marbles
b. four index cards printed with either an uppercase or lowercase letter
c. two small, plastic balls attached to a larger plastic ball by toothpicks
d. a large, plastic bucket filled with dirt, dead leaves, and rocks

C. Two small, plastic balls attached to a larger plastic ball by toothpicks

Explanation:

One molecule of water has 1 oxygen atom and two atoms of hydrogen. Each hydrogen is attached to the oxygen by a simple bond, they share one pair of electron.

Because oxygen is larger than hydrogen, a manner to represent a single molecule is to have two small plastic balls (representing hydrogen) attached to a larger plastic ball (representing oxygen) by toothpicks (representing the bonds), such as the image below.

answer: your mm

explanation:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
