You have a material which consists of only carbon and hydrogen atoms in the lab. This material is burning with air in the lab reactor. In the product flow, you found out that there are $10$ mole$\%$ oxygen, $4$ mole $\%$ carbon monoxide, $78$ mole$\%$ nitrogen, $8$ mole $\%$ carbon dioxide. Please calculate the moles of carbon and hydrogen and also moles of air in the input flow. Please calculate the moles of water in the product flow. Please draw the flowchart and do the degree of freedom analysis. $($Note: air contains $21\%$ oxygen and the rest is nitrogen.$)$
