What is c2 chemistry?
Diatomic carbon (systematically named dicarbon and 1λ2,2λ2-ethene), is a green, gaseous inorganic chemical with the chemical formula C=C (also written [C2] or C2. It occurs in carbon vapor, for example in electric arcs; in comets, stellar atmospheres, and the interstellar medium; and in blue hydrocarbon flames.
What is a dilute acid GCSE?
Concentrated and dilute acids A dilute acid has the acid molecules mixed with a large amount of water, so that there is only a low concentration of H + ions. Concentrated acids have little to no water molecules mixed with the acid molecules, meaning the concentration of H + ions is high.
