The product of a reaction between isobutyl heptanoate and water in the presence of a base is .

Isobutanol and Sodium Heptanoate

Explanation:

Isobutyl heptanoate is a chemical compound which is a form of fatty acids. The reaction of isobutyl heptanoate with water will give rise to two different chemical compounds. The ions breaks the molecules of isobutyl when introduced with base. The give rise to sodium heptanoate molecules by a chemical process.

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.
