Why are substances such as coal and gasoline used as fuel sources? A. They have high kinetic energy, which can be converted into electrical or mechanical
energy
B. They have large amounts of energy stored in the chemical bonds which can be
converted into kinetic energy when combusted
C. They are able to easily make endothermic reactions, which can be harnessed and
converted into mechanical energy
D. None of the above statements are true

A.They have high kinetic energy, which can be converted into electrical or mechanical energy

Explanation:

The kinetic energy of the fast-moving water turns turbines, which drive generators that produce electricity. The energy in fossil fuels (coal, oil, gas) is Chemical Potential Energy.

no

explanation:

go away, people want answers, not to hook up

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.
