12.5g of zinc carbonate is heated, it decomposes to make 8.1g of zinc carbonate. Calculate the mass of carbon dioxide made.
Answers
Answer:
zinc carbonate(ZnCO3), a mineral ore of zinc. Historically, smithsonite was identified with hemimorphitebefore it was realized that they were two different minerals. The two minerals are very similar in appearance and the term calaminehas been used for both, leading to some confusion. The distinct mineral smithsonite was named in 1832 by François Sulpice Beudant in honor of English chemist and mineralogist James Smithson (c.1765–1829), whose bequest established the Smithsonian Institution and who first identified the mineral in 1802.
