Hydrogen - Wikipedia

Hydrogen gas was first artificially produced in the early 16th century by the reaction of acids on metals. In 1766–81, Henry Cavendish was the first to recognize that hydrogen gas was a discrete substance, [9] and that it produces water when burned, the property for which it was later named: in Greek, hydrogen means "water-former".

What volume of hydrogen at STP is produced when 2.5 g of

Feb 28, 2016· 0.86 "L" 1 "mol" of "Zn" has mass of 65.39 "g". The amount of "Zn" is frac{2.5 "g"}{65.39 "g/mol"} = 0.038 "mol". The amount of "H"_2 produced is the same as the amount of "Zn" consumed (0.038 "mol"). 1 "mol" of ideal gas will occupy 22.4 "L" at STP. The "H"_2 will occupy 0.038 "mol" xx 22.4 "L/mol" = 0.86 "L".
