A chemist forms 16.6 g of potassium iodide by combining 3.9 g of potassium with 12.7 g of iodine. Show that these results are consistent with the law of conservation of mass.

Answer :

ermilusrebecca14
3.9 g + 12.7 g = 16.6 g

The sum of the masses of potassium and iodine equals the mass of the product, potassium iodide. The results are consistent with he law of conservation of mass.


Hope this heeeelllllllpppppppp

The law of conservation of mass states that mass can neither be created nor destroyed by chemical reactions or physical transformations.

The mass of potassium iodide can be calculated from the sum of the mass of potassium and iodine.

The mass of potassium iodide is as follows:-

[tex]Mass\ of \ potassium\ iodide=3.9\ g+12.7\ g\\=16.6\ g[/tex]

So, the total mass of potassium iodide is equal to the mass of potassium plus iodine. So, these results are consistent with the law of conservation of mass.
