Can someone me out? can't seem to chose between a or d water (h2o) is composed of the same elements as hydrogen peroxide (h2o2). why do these substances have different properties? the atoms are arranged differently in each molecule. the molecules are the same. the atoms are the same. water has more atoms than hydrogen peroxide. i know its not c

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.

the answers would be

the first one and the second one
