As a result of the C + O2 = CO2 reaction, a product stream is obtained with a molar flow of 3000 kmol/h. Two streams of raw materials are fed to the reactor: the first one consisting of 50% C and 50% Si and the other containing 100% of O2 . Raw materials are given in a ratio of C:O2 equal to 1:3. All coal is burned in the process. Calculate values of all streams and mole fractions
