Question

Can someone help me out? can't seem to chose between A or D

Answer 1

It definitely isn't c so I think u should go with choice a

Answer 2

Answer:

The atoms are arranged differently in each molecule.

Step-by-step explanation:

In H₂O, the bonds are arranged in the order H-O-H. In H₂O₂, they are in the order H-O-O-H.

The O-O bond in hydrogen peroxide is so weak that H₂O₂ tends to explode.

Water has only strong O-H bonds, so it is quite stable.

B is wrong. The molecules have different formulas, so they are different compounds.

C is wrong. The atoms are the same, but their different arrangement causes different properties.

D is wrong. A molecule of water has fewer atoms than one of hydrogen peroxide.
