Which of the following is true about how hydrogen and oxygen can combine to form molecules?

• Hydrogen and oxygen can combine in many ways to form different molecules.

• Molecules composed of hydrogen and oxygen must have at least four atoms.

• Two atoms of hydrogen are always required to bond with two atoms of oxygen.

• When oxygen combines with hydrogen to make a molecule, water will always be produced.

Which of the following is the most accurate evaluation of these models?

• Only Students 1, 2, and 4 created acceptable models, since molecules must be made of different types of atoms.

• All of the students created acceptable models because molecules can consist of many different configurations of atoms.

• Only Student 2 created an acceptable model of a molecule, since every molecule must have a balance of atoms.

• All student models are acceptable except that of Student 4, since molecules can't be made of so high a number of atoms.
