3. The producer gas made from the coke has the following composition :
CO : 28%, CO2 : 3.5%, O2 : 0.5% and N2 : 68%.
The gas burned with such a quantity of air that the oxygen from air is 20% in excess of the net oxygen required for complete combustion. If the combustion is 98% complete, calculate the weight of the gaseous product formed. Given the oxidation reaction as below:
CO + ½ O2  CO2

The water-gas shift reaction plays a central role in the chemical methods of obtaining clean fuels from coal.

CO (g) + H2O (g)= CO2 (g) + H2 (g)

A study was made in which equilibrium was reached with [CO]=[H2O]=[H2]=0.100M and [CO2]=0.400M. After 0.800 mol of H2 is added to the 2.00L container and equilibrium is reestablished, what are the new concentrations of all the components?

Vaughn Co. is a retail store operating in a state with a 7% retail sales tax. The retailer may keep 2% of the sales tax collected. Vaughn Co. records the sales tax in the Sales Revenue account. The amount recorded in the Sales Revenue account during May was $747930.

A mixture of water and graphite is heated to 600 K . When the system comes to equilibrium it contains 0.11 mol of H 2 , 0.11 mol of CO , 0.31 mol of H 2 O , and some graphite. Some O 2 is added to the system and a spark is applied so that the H 2 reacts completely with the O 2 . Find the amount of CO in the flask when the system returns to equilibrium.

JB Co. is planning to invest in a new koala theme park. The investment will generate $4.5 million p.a. for 15 years with the first cash inflow received in one year's time. The required rate of return for this type of investment is expected to be 6% p.a. for years 1-9 rising to 11% p.a. for years 10-15. What is the most JB Co. should pay for this investment now?

The supplies adjustment records the office supplies used for the month. A co-worker asks you to record a larger supplies adjustment compared to what is leftover so the extra supplies can be used at a nonprofit organization.

Respond to the following in a minimum of 175 words:

• Would you do as your co-worker requests so the nonprofit organization can have these extra supplies? Why or why not?

100 lbmoles of Methane is feed into a partial oxidizer with 160 lbmoles of dry air which also contains water(humidity = 0.050 lb water/lb dry air). The methane partially oxidizes to produce CO according to: CH4 + 3/2 O2 —> CO + 2H2O If the outlet gas contains 45.00% (mole %, wet basis) nitrogen, what is the reaction conversion based on the limiting reactant?
