Methane is CH4 and thus made of C = carbon and H = Hydrogen.
Methane contain 1 carbon & 4 hydrogen elements.
C, H, N, O
The elements that must combine to make sugar (sucrose) are C, H and O (using symbols). These represent carbon, hydrogen and oxygen, respectively.
This is because there is not enough letters for all the elements if they were all with one letter and they would have to to repeat the letters again and you wouldn't know which element is which and if there was two letters it would be much much easier for you too know,so you could get the initial of the element.....:). ( it took me awhile to figure it out...) hope you understand it...
The chemical symbols of a highlighter typically include compounds like C(NH2)3, CH3COOC2H5, and C4H4N2. These compounds are commonly found in the fluorescent ink used in highlighters to create bright colors.
Methane contain 1 carbon & 4 hydrogen elements.
The chemical formula of methane is CH4.C is the chemical symbol of carbon and H is the chemical symbol oh hydrogen.Methane is the most simple hydrocarbon and is an indispensable fuel.
Not all elements can be identified by a single letter. For example, Carbon (C) and Chlorine (Cl) both start with a "C" and have "C"'s in their symbols. Another letter had to be added to distinguish the two. Also, the Periodic Table has over 100 elements and there would not be enough letters to cover them all if they were only single letters.
Carbon (C) Hydrogen (H) Iron (Fe)
Two, as indicated by the presence of only two distinct atomic symbols in the formula.
No, its formula shows that is a compound of hydrogen (H) and carbon (C).
All elements that don't currently have IUPAC systematic placeholder names have one or two letter chemical symbols. So, currently, elements 1 (Hydrogen) to 112 (Copernicium) have one or two letter symbols.
C, H, N, O
H = Hydrogen, C = Carbon, O = Oxygen, and N = Nitrogen. These are the Symbols for these four "proteinaceous" Elements.
If you look at the periodic table (go to webelements.com to see one if you dont have one) the symbol is the letter or two in the middle of each square. For example, the symbol for Hydrogen is "H", the symbol for Potassium is "K", the symbol for neon is "Ne" & The symbol for Carbon is "C". The symbol is always one or two letters, except for the last few elements, which for now have 3, until they get real names.
There is no element with the symbol "hc." It is possible that the symbols "H" and "C" were combined, which would refer to hydrogen (H) and carbon (C), two separate elements on the periodic table.
Q = {a,b,c}
