There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide: 2Cu2S(s)+3O2(g) --> 2Cu2O(s)+2SO2(g) In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: Cu2O(s)+C(s) --> 2Cu(s)+CO(g) Write the net chemical equation for the production of copper from copper(I) sulfide, oxygen, and carbon. Be sure your equation is balanced.

The chemical equations below show reactions similar to those you have met already. One of them is balanced correctly, and three are not. Identify which one is correctly balanced. State why.  - 4 Fe (s) + 3 O2 (g) = 2 Fe2O3 (s) - Mg (s) + O2 (g) = 2 MgO (s) - 2 K (s) + 2 O2 (g) = 2 K2O (s) - 2 Na (s) + H2O (l) = 2 NaOH + H2 (g)

Hematite, Fe₂O3, is an important ore of iron. (An ore is a natural substance from which the metal can be profitably obtained.) The free metal is obtained by reacting hematite with carbon monoxide, CO, in a blast furnace. Carbon monoxide is formed in the furnace by partial combustion of carbon. The reaction is Fe₂O3(s) + 3CO(g) → 2Fe(s) + 3CO₂(g) How many grams of iron can be produced from 1.34 kg Fe₂03? g Fe

Looking up one snowy afternoon from a book titled The Moral Case Against Turning Lead Into Gold (Or Vice Versa), your friend Hans (an expert chemist) says this: "Many metals can be produced from their oxide ores by reaction at high temperatures with carbon monoxide. Carbon dioxide is a byproduct." Using Hans's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced!   Fe2O3(s) + CO(g) ->
