Question

For each of the changes described, decide whether two or more elements formed a compound or if a compound decomposed (to form elements or other compounds). Explain your reasoning in each case. (a) Upon heating, a blue powder turned white and lost mass. (b) A white solid forms three different gases when heated. The total mass of the gases is the same as that of the solid.

For each of the changes described, decide whether two or more elements formed a compound or if a compound decomposed (to form elements or other compounds). Explain your reasoning in each case. (a) After a reddish-colored metal is placed in a flame, it turns black and has a higher mass.

For each of the following, determine if the change is physical or chemical AND if the material is a mixture or pure compound/element. a) A colorless, crystalline, clear solid is heated and forms a pale yellow-green gas; a shiny, malleable metal is left behind. b) A brown liquid is heated and a colorless, aromatic liquid is produced with a clear, colorless liquid while a brown liquid is left behind in the container. c) A shiny, dark gray metal and a clear colorless gas combine to form a flaky orange solid.
