Why are water and hydrogen peroxide different substances even though they are both made up of hydrogen and oxygen atoms

But because they have different molecular structures, they have very different chemical properties: water is a stable molecule, while hydrogen peroxide is unstable due to the bond between the two oxygen atoms (this is why over time, hydrogen peroxide will give off oxygen gas and turn into plain old water).

Explanation:

small = small current large mag large current

c) up is the direction the magnetic force is acting on the charge.
