Answer:Most naturally-coloured diamonds are created when trace elements interact with the carbon atoms during the diamond's creation. The presence of chemical elements such as nitrogen, sulphur, and boron can colour diamonds in shades of yellow, green, and blue. ... Trace elements have never been found in pink diamonds.
in other words it depends on the heat of how it is made
Redox: involve the transfer of electrons between two chemical species. The compound that loses an electron is said to be oxidized, the one that gains an electron is said to be reduced. There are also specific terms that describe the specific chemical species.
Substitution:A substitution reaction is a type of chemical reaction where an atom or functional group of a molecule is replaced by another atom or functional group.
Combustion: a chemical reaction chemical that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light.
So it is Redox
Hope that helped :D
Pollution because it’s one of the reasons for global warming, and global warming causes habitat destruction causing many organisms to become extinct
Answer:
A) 
Explanation:
m = Mass of water = 38.9
M = Molar mass of water = 18 g/mol
= Avogadro's number = 
The reaction of electrolysis would be
Number of moles of 
From the reaction it can be seen that 2 moles of gives 1 mole of 
So, number of moles of produced is
Number of molecules
So, of oxygen is produced.
