Students are preforming a lab experiment in chemistry class where they must find out what 3 mystery solutions are. The bottles are not labeled,
but one of the bottles contains NaCl, another bottle contains AgNO3, and
another bottle contains K SO.. The students decide to mix one drop of
each unknown chemical with one drop of some known chemicals to see if
precipitates form in order to identify the unknown chemicals. Use the data
table below to determine each unknown.*

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.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
