Can u guys help me with this homework please?

1- A coal combustion batch reactor produces CO2 as a product. How of each of the following are contained in 100.0g of CO2 (molecular weight (MW) = 44g gmole)? (1) mole CO2; (2) Ib-moles CO2; (3) mole C; (4) mole O; (5) mole O2;(6) g O2;(7) molecules of CO2. 2- A refinery stack emits gas mixture of 15%CO2,10%CO,5%H,35%N2, 10%O2 and the balance H2O (in mole % ). The mixture is flowing at rate of 1500kg/min. a- Calculate the mass\% of the mixture. b- Calculate the average molecular weight. c- Calculate the total molar flow rate in Kmole/hr. d- Calculate the mass flow rate of CO2. 3- The gaseous effluent of a combustion reactor has the following composition by mass: What is the molar composition? What is the average molecular weight? 4. What are the factors that control the rate of a chemical reaction? Show the effect of each factor. 5- List some common reactions that occur in the world around you and compare their rates. Try to think of some that are fast and some that are slow
