The electrolytic manufacture of chlorine gas from a sodium chloride solution is carried out by the following reaction: NaCl + H₂O →→→→ NaOH + H₂ + Cl₂ The starting amount of the sodium chloride solution is 10 m³ containing 50% by weight of NaCl and its specific gravity relative to water at 4°C is 1.07. a. What is the density of the solution? b. How many kilogram of NaCl are in the solution? c. How many kilograms of Cl2 will be produced?

At approximately atmospheric pressure, methane gas is burned completely with 30% excess air. Both the air and methane enter the furnace at 30 °C saturated with water vapor, and the flue gases leave the furnace at 1500 °C. Calculate how much heat is lost from the furnace per mole of methane. In your solution, show analytically all calculations, including the analytical derivation of the number of moles of water vapor entering the furnace. Use steam tables to determine Psat, and compare your answer with the answer you would obtain using Antoine’s and Wagner’s equations. For the latter, you can determine A, B, C, D as in ** above.

A gas containing argon, benzene, toluene is in equilibrium with 35 mol% Benzene and 65 mol % toluene liquid mixture at 85 C degrees and 10 atm. Determine the gas phase composition.

The fuel in the form of biogas (65%-mol CH4 and 35%-mol CO2) is burned in a furnace. In order for combustion to take place stoichiometrically, calculate the air to fuel ratio (vol/vol) from this problem!
