Mostly just carbon and hydrogen. A wax sort of a "hydrocarbon" with some oxygen.
The carbon and hydrogen present in the fuel react with the oxygen that taken inside cylinder during induction and the explosion takes place.
because there are 2 hydrogen atoms in the molecule of hydrogen atoms
Hydrogen peroxide (H2O2) contains two atoms of hydrogen and two atoms of oxygen for a total of four atoms.
To answer your question on how many hydrogen atoms are there in caffeine, the scientific answer would be 10 atoms of hydrogen.
The SUN does NOT BURN gas. It is a FUSION of hydrogen atoms into helium atoms.
Carbon and Hydrogen
Carbon and hydrogen atoms mostly make up lipids.
No. The sun's energy comes from the nuclear fusion of hydrogen, not combustion. In this reaction hydrogen atoms fuse with one another to form helium atoms. The fusion of hydrogen yields about 4.5 million times more energy than you would get from burning the same amount.
They are mostly just hydrocarbons - chains of Carbon with Hydrogen atoms hanging off the sides and ends.
Lipids (wax, fats and oils)
Mostly hydrogen bonds.
mostly fusion, where hydrogen atoms combine to form helium atoms
Burning hydrogen combines the hydrogen with oxygen atoms. This yields H2O also known as water.
Burning releases heat by the formation of chemical bonds between the atoms that are burning. An example is hydrogen burning with oxygen, because when the atoms are bonded together as water they have less total energy than when the atoms are separated. It takes energy to separate out hydrogen and oxygen from water (by electrolysis for example), and this is the energy that is released when the separate atoms are re-bonded in burning.
Hydrogen is composed of hydrogen atoms.
