Question

After comparing the two molecules: H-O-H and H-O-O-H, which of the following are true?

Option 1: Both have the same composition. (True, both molecules have the same composition in terms of the elements present: hydrogen and oxygen.)

Option 2: Both have different properties. (True, they have different properties because the arrangement of atoms and the number of oxygen atoms are different.)

Option 3: Both have the same structure. (False, they have different structures as indicated by their chemical formulas.)

Option 4: Both have different composition and structure. (False, they have the same composition but different structures.)

Answer 1

The two molecules H-O-H and H-O-O-H have the same composition but different properties and structures.

Step-by-step explanation:

The two molecules H-O-H and H-O-O-H have the same composition, as they both contain hydrogen and oxygen atoms. However, they have different properties and structures. Option 1 is true because both molecules have the same composition. Option 2 is also true because the arrangement of atoms and the number of oxygen atoms differ between the two molecules. Option 3 is false, as they have different structures indicated by their chemical formulas. Option 4 is also false, as they have the same composition but different structures.
