2. The element silicon can be produced from sand (SiO2) and silicon carbide (SiC – also called carborundum) at high temperature according to the equation. Molar Mass: SiO2 - 60.1 g; Si - 28.09 g; SiC - 40.11 g; CO -28.01 g

2 SiC(s) + SiO2 (s) → 3 Si (s) + 2CO (g)

Suppose you want to produce 75.0 g of silicon.

a, What mass (g) of silicon dioxide and silicon carbide are needed to react.

b. What mass (g) of carbon monoxide is formed in the reaction?

1. The integrated circuits in your cell phone and computer are made from the semiconductor silicon. The silicon is obtained from a really inexpensive starting material, sand, which is primarily silicon dioxide (SiO2). One step in the purification of silicon is to separate it from its solid impurities by forming the gas silicon tetrachloride (SiCl4). Given the following reactions, what is the overall enthalpy change in converting 1 mol of silicon dioxide into pure silicon? SiO2(s) + 2C(s) → Si(impure, s)...
