The same amount of energy released when they recombine
Yes, the energy required to separate water into O2 and H2 is at least equal to the energy released when these gases come together to form water.
<h3>What is the process for separating water into it's constituents ?</h3>
The process of separating water into hydrogen and oxygen is known as electrolysis. This reaction occurs in a device known as an electrolyzer.
- This is around 260 kJ per mole of water, or just under 5 eV per water molecule (4 electrons times 1.23 V). One litre of water would require at least 16 MJ (4.4 kWh) in order to be split, which is more energy than would be required to send one litre of water into deep space.

Answer:
the particles of the rock possess kinetic energy as they stay in a place the particles also contain potential energy due to their position and arrangement This form of stored energy is responsible for keeping the particles together

C) is the best description, although a scientific theory is not necessarily a "fact". They are, however, based on evidence.
A) is complete garbage.
B) is a good description of a scientific "law"- something that predicts how a certain event will occur without explaining why this is (for instance, the law of gravity accurately describes the gravitational forces between two bodies, but does not explain why these forces are there).
D) is a scientific "hypothesis"- an explanation for an observed phenomena that is yet to be proven.
