Final answer:
The molecular formula to represent ten molecules of hydrogen peroxide is 10H2O2, which includes twenty hydrogen and twenty oxygen atoms. The overall molecule has a bent geometry, resulting in a non-linear shape.
Step-by-step explanation:
The molecular formula to represent ten molecules of hydrogen peroxide (H2O2) is 10H2O2. Each molecule of hydrogen peroxide consists of 2 hydrogen atoms and 2 oxygen atoms. When indicating ten molecules, you multiply the subscript of each element in the formula by ten, resulting in twenty hydrogen atoms (2 x 10) and twenty oxygen atoms (2 x 10) in total.
Regarding the geometry of hydrogen peroxide, each central oxygen atom has a bent shape due to the two hydrogen atoms and one additional oxygen atom it is bonded to, which imparts an angular or V-shaped geometry to the molecule as a whole. The structure and bond angles in hydrogen peroxide also result in the molecule having a non-linear shape, distinguishing it from the linear diatomic molecule molecular oxygen (O2), which consists of two doubly bonded oxygen atoms and is not classified as a compound but a homonuclear molecule.
