10. Which of the images below represent balanced chemical equations? Write balance chemical equations for any images are unbalanced as drawn. The red spheres represent oxygen, black represent carbon, blue represent nitrogen, and yellow represent sulfur. (a) (c) (b) (d) ↑

In ancient China, copper was first isolated around 475 BC. Since then, methods of producing copper have advanced. Most copper is mined or extracted as copper sulfides from large open pit mines. One method includes using iron to replace copper in a copper (II) sulfate solution.  Which of the following is a correct chemical equation for this method?

Many computer chips are manufactured from silicon, which occurs in nature as SiO2. When SiO2 is heated to melting, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. In an industrial preparation of silicon, 155.2 kg of SiO2 is allowed to react with 77.5 kg of carbon to produce 66.2 kg of silicon. Determine the theoretical yield  and percent yield for the reaction.

3) P, + 5 02 → P,010 When elemental phosphorus oxidizes, it produces a covalently bonded molecule known as tetraphosphorus decoxide. What is the limiting reactant if 1.33 g of P4 reacts with 5.07 g of oxygen gas? What is the theoretical yield of P.O10?
