Chapter 2, Problem 4QAP
Two basic laws of chemistry are the law of conservation of mass and the law of constant composition. Which of these laws (if any) do the following statements illustrate?
(a) The mass of phosphorus, P, combined with one gram of hydrogen, H, in the highly toxic gas phosphene, PH3, is a little more than twice the mass of nitrogen, N, combined with one gram of hydrogen in ammonia gas, NH3.
(b) A cold pack has the same mass before and after the seal between two reactants is broken to allow reaction to occur.
(c) It is highly improbable that carbon monoxide gas found in Los Angeles is C1.2O1.1.
