Silicon is a semiconductor, making it valuable for electronics. Fortunately, silicon can be obtained from a very inexpensive and readily available source: sand (primarily silicon dioxide). To isolate the silicon, one of the initial steps is to form the gas silicon tetrachloride. Calculate the enthalpy change (in kJ) using Hess's Law in the conversion of 1.00mol of pure sand into pure silicon.
