How discovered hydrogen
WebHe made several key observations: A, T, C, and G were not found in equal quantities (as some models at the time would have predicted) The amounts of the bases varied among species, but not between individuals of the same species The amount of A always equalled the amount of T, and the amount of C always equalled the amount of G (A = T and G = C) Webhydrogen cyanide, also called formonitrile (HCN), a highly volatile, colourless, and extremely poisonous liquid (boiling point 26° C [79° F], freezing point -14° C [7° F]). A solution of hydrogen cyanide in water is called hydrocyanic acid, or prussic acid. It was discovered in 1782 by a Swedish chemist, Carl Wilhelm Scheele, who prepared it from the pigment …
