Which of the following has paired the correct compound name with the chemical formula? a Na2Cr2O7 - sodium dichromate b KClO3 - potassium perchlorate c Mg3(PO4)2 - magnesium(II) phosphate d CuO - copper oxide

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

there are two significant figures.
