Answer:
Structural formula shows the atoms and bondsin an organic compound.
Explanation:
Structural formula of methane shows
1 Carbon atom is singly bonded to 4 hydrogen atoms.
Answer:
Two molecules of hydrogen combine with two molecules of oxygen to form hydrogen peroxide. Hence, its chemical formula is H2O2. It is the simplest peroxide (since it is a compound with an oxygen-oxygen single bond). Hydrogen peroxide has basic uses as an oxidizer, bleaching agent and antiseptic
In an orderly, repeating, three-dimensional pattern called a crystal lattice.
Answer:
