Question

Mr. Stein builds a model of a molecule out of wooden beads and pegs. He uses the model to explain the shape of the molecule. Mr. Stein uses a model because
A: the real molecule is too small to easily observe.

B: the model makes it more difficult to understand the molecule's shape.

C: the real molecule doesn't actually have a shape.

D: the bonds between the atoms in the real molecule are too strong.

Answer 1

Answer:

A: the real molecule is too small to easily observe.

Explanation:

Mr. Stein wishes to facilitate understanding of the formula and a molecule and the bonds that provide such a formula. He knows that it will be much easier for his students to understand if they visualize the molecule. The problem is that molecules are extremely small, making it impossible to see them with the naked eye, and even more impossible to see the chemical bonds that allow the molecule to have the shape it has.

So that the students could visualize the structure of the molecule, Mr. Stein decided to build a model of a molecule out of wooden beads and pegs.

Answer 2

Answer:

A

Explanation: The real molecule is too small so had to build a model to make it viewable
