Molecules may be similar or different on the basis of size, shape, structure and chemical composition.
<h2>Similarities and differences</h2>
Two molecules can be considered similar or different on the basis of size, shape, structure and chemical composition. The molecules in the two proposed systems are consider the same when they are similar in size, shapes, structure and chemical composition.
While on the other hand, the molecules is considered different when they have different structure and chemical composition so we can say that molecules may be similar or different on the basis of size, shape, structure and chemical composition.

Answer:
Density, 
Explanation:
It is given that, placing a sample of iron (II) oxide into a graduated cylinder makes the water volume increase 12.0 mL.
It means that the volume of the sample is 12 mL
The weight of the sample is 76.6 g
We need to find the density of the sample.
12 mL = 12 cm³
The formula of density is given by :
So, the density of the sample is 
.
Answer:
Explanation:

The equator gets the most sun and has the warmest climate. This has to do with the tilt of the Earth on it’s axis. As you go north or south from the equator toward the poles the Earth’s temperature gets colder. It is harder for the sun’s direct rays & the curvature of the Earth to reach these points This has to do with the direct sunlight that reaches the equator. Think of a ball, or take a flashlight & shine it on a ball to see this yourself from different angles. The angle of the sun on the the Earth also causes different seasons.
