Hydrogen peroxide and water both contain the same two elements. write their chemical formulas. compare and contrast their properties. explain the importance of writing correct chemical formulas

Hydrogen peroxide and water contain hydrogen and oxygen.
chemical formula of hydrogen peroxide is h2o2 and of water is h2o.
hydrogen peroxide  (h2o2) is a colorless liquid that resembles water in many respects. its physical properties are very similar to those of water, except that it is 40% denser. the main difference between hydrogen peroxide and water, however, is in its chemical behavior. the single bond between the two oxygen atoms is weak, so that h2o2  readily fragments into either h and ho2  or two ohs. either way, the resulting species are free radicals, which means they are very reactive, and this makes h2o2  a very powerful oxidizing agent. for this reason, it has been utilized in rocket propulsion, when it is used to oxidase the  hydrazine  fuel, liberating hot gases (steam and oxygen) which propel the rocket forward.
if the chemical formula is wrong, their weights, density, volume moles etc will be wrong.
