Question

part b are all the molecules in the picture the same? explain.

Explanation:

To answer this, one would need to visually inspect the molecules in the picture. If they have the same atoms and same bonding - patterns, they are the same. If different atoms or bonding exists, they are different. Since the picture is not provided, a definite answer cannot be given. But in general, we look at the elemental composition and molecular structure to determine if molecules are the same.

Answer:

Without seeing the picture, it is impossible to determine if all the molecules in the picture are the same.
