A tank of syngas produced by coal gasification contains 60.0% carbon monoxide, 30.0% hydrogen, and 10.0% carbon dioxide. What is the mass of hydrogen (in g) in 1.00 cubic meter of this syngas mixture at 1.00 atm and 25.0 °C? (1 m³ = 1000 L)

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

14 days is the half-life of phosphorus-32
