In a dehydration process , the product , which was 80\% moisture , has lost half of its weight during drying. What is the final moisture content

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.

a polar bond is formed when electrons are shared unevenly between atoms
