H-H in chemicatry means 'H2'. That is two atoms of hydrogen , which singly covalently bonded to each other.
The dash mark (-) signifies a bond. In the case of H-H, two hydrogen atoms are bonded.
hydrogen
Chemistry is divided into three divisions. Organic Chemistry ; dealing with the chemisgtry of carbon , hence 'C-H' bonds'. Inorganic Chemistry ; dealing with non-carbon chemistry. Physical Chemistry ; dealing with the physical changes, energy, stoichiometry, and calculations.
"H" stands for Hydrogen in the periodic table.
Yes all chemistry comes from physical chemistry. Organic chemistry is the reaction of organic molecules (those with C-H bonds). How those reactions happen is physical chemistry i.e. think thermodynamics.
In the chemistry formula, H2O, the "H" stands for hydrogen. The "O" stands for oxygen.
In chemistry C represent Carbon, O represents Oxygen, N represents Nitrogen, and H represents Hydrogen. These are all the most common elements in organic chemistry.
