Question:

One material needed to make silicones is dichlorodimethylsilane, (CH3)2SiCl2. It is made by treating silicon powder at about 300°C with CH3Cl in the presence of a copper-containing catalyst.
(a) Write a balanced equation for the reaction.
(b) Assume you carry out the reaction on a small scale with 2.65 g of silicon. To measure the CH3Cl gas, you fill a 5.60-L flask at 24.5°C. What pressure of CH3Cl gas must you have in the flask to have the stoichiometrically correct amount of the compound?
(c) What mass of (CH3)2SiCl2 can be produced from 2.65 g of Si and excess CH3Cl
