write a chemical formula for nitrous oxide ( laughing gas) that is made up of two atoms of nitrogen and one atom of oxygen. also, write the chemicl formula of hydrogen peroxide made up of twoatoms of hydrogen and two atoms of oxygen.

 N(2)O

 Nitrous oxide, commonly known as laughing gas or sweet air, is a chemical compound with the formula N₂O. It is an oxide of nitrogen. At room temperature, it is a colorless non-flammablegas, with a slightly sweet odor and taste. It is used in surgery and dentistry for its anesthetic effects. It is known as "laughing gas" due to the euphoric effects of inhaling it, a property that has led to its recreational  anesthetic. Nitrous oxide gives rise to NO (nitric oxide) on reaction with oxygen atoms, and this NO in turn reacts with ozone.

 nitrous oxide=NO2 hydrogen peroxide=H2O2

NO2

 the chemical formula for nitrous oxide is n2o

N₂O,H₂0₂ RESPECTIVELY.

Actually the formula is N₂O.
