(c) assuming the the density of the solid is 6.32 g/cm3 and that of the liquid is 7.14 g/cm3, determine the amount of each phase in vol%. See attached image

Nitrogen dioxide, a pollutant in the atmosphere, can combine with water to form nitric acid. One of the possible reactions is shown here. Calculate ΔG° and Kp for this reaction at 25 °C and comment on the spontaneity of the reaction.3 NO2( g) + H2O(l )------->2 HNO3(aq) + NO( g)

The results of air temperature measurement obtained a dry bulb temperature of 37 ° C and a wet bulb temperature of 27.5 ° C. Using a psychrometric chart, determine the properties of the air as follows:a. RH:%b. Water content: kg water / kg airc. Specific volume: m3 / kgd. Enthalpy: kJ / kge. Condensation temperature: ° CIf the air is within 162 m3 space, determinef. Air weight (dry air and water vapor): kgg. the amount of water content in the space: kg

A rectifying column consists of a tube arranged vertically and supplied at the bottom with a mixture of benzene and toluene as vapor. At the top, a condenser returns some of the product as a reflux which flows in a thin film down the inner wall of the tube. At one point in the column, the vapor contains 60 mol% benzene and the adjacent liquid reflux contains 51 mol% benzene. The temperature at this point is 92°C. Assuming the diffusional resistance to vapor transfer to be equivalent to the diffusional resistance of a štagnant vapor layer 0.5 mm thick, calculate the rate of interchange of benzene and toluene between vapor and liquid. The molar latent heats of the two materials can be taken as equal. The vapour pressure of toluene at 92°C is 44.0 kN/m2 and the diffusivity of the vapors is 0.053 cm?/s.

The air at a dry ball temperature of 80 oC and 4 % RH is passed over the cooling coil so that the air dry ball temperature becomes 35 oC. how much heat is released from the air in the process? =          (kJ / kg)

A saturated solution containing 150 kilograms of sodium sulfate (mol. wt. = 142) in 600 kilograms of water is fed to Swenson-Walker crystallizer. The solubility of sodium sulfate at 10 °C is 9 kilogram of anhydrous salt per 100 kilogram of water, and the deposited crystals consist of the decahydrate (mol. Wt. = 322). Crystallization is by cooling at 10 °C. If 2% of the water was lost by evaporation during the cooling process, the percent (%) yield in the crystallizer is Blank 1%. **(Express your answer to two (2) decimal places.
