FORMAL LAB REPORT INTRODUCTION John Dalton’s atomic theory states that elements combine in simple numerical ratios to form compounds. A compound‚ no matter how it is formed‚ always contains the same elements in the same proportion by weight. The law of mass conservation states that mass can neither be created nor destroyed. In this experiment‚ the mass of the metal was not destroyed or created; the metal’s mass was simply changed into a compound form once the gas
