Need help T~T. It's chemistry.

Which formula can be used to calculate the molar mass of hydrogen peroxide

Atoms contain subatomic particles called protons and neutrons. when these protons and neutrons spilt, a lot of energy is released

Which statement justifies that hydrogen peroxide (h2o2) is a polar molecule? the o – h bond is nonpolar and the molecule is asymmetric. the o – h bond is nonpolar and the molecule is symmetric. the o – h bond is polar and the molecule is asymmetric. the o – h bond is polar and the molecule is symmetric.
