please solve the problem using material balance with chemical reaction, please draw process diagram.

One method to obtain pure silicon is through a process where the following reactions:  SiO2 +2C---Si +2CO Si + 2Cl2---SiCl4 SiCl4+2Mg---2MgCl2 +Si In one particular case, 100 pounds of a solid mixture containing 51.94% SiO2, 15.58% C and 32.48% Mg together with 0.13 mol-lb of Chlorine gas (Cl2), obtaining as a product 76.05 pounds of solid product and a gaseous mixture whose molar composition is 2.28% Cl2, 1.21% SiCl4, and 96.51% CO. Find: i) The percentage excess of the reaction. ii) The conversion of the three reactions. iii) The weight composition of the final solid product. iv) The pounds of silicon produced.
