Abattery can provide a current of 4.60 a at 3.40 v for 2.50 hr. how much energy (in kj) is produced? 1st attempt kj energy

The energy produced equals 140.760 kJ

Explanation:

The relation between power, current and voltage is

Applying the given values in the relation above we get

Now Since

Again applying the calculated values we get

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.
