Two aqueous sulfuric acid solutions are available at a processing facility: a. 20.0 wt% H2SO4 (sg = 1.139) b. 60.0 wt% H2SO4 (sg = 1.498) It is desired to mix the two solutions such that the final product has a concentration of 4.00 M (sg = 1.213). There is 100 kg of the 20% solution available. If all of this is to be used, calculate: a. The mass of 60% solution needed b. The mass and composition of the final product

#3 The first step in the reaction sequence for the production of nitric acid via the oxidation of ammonia is: 4NH3 + 502 2 4NO + 6H2O 75% conversion is achieved with an equimolar mixture of ammonia and oxygen fed at the rate of 100 mol/h. Determine the outlet compositions. (Hint: determine the limiting reactant).

A batch process is operated with the following sequence. The feed to the batch process consists of a solution of 500 L of ethanol with 120 mole of A and 120 mole of B. If the temperature of the solution is sufficient, A and B will react to form P (the desired product): A (eth) + B (eth) → P (s) DHreact  = − 250 kJ/mol (1)  product P is sparingly soluble in ethanol, which helps facilitate its removal from the reaction solution. It can be assumed that the reaction rate is first-order in both the concentration of A (cA ) and B (cB ), and so second-order overall: -r A = k c A cB  (2) The batch process consists of the following FOUR steps: Initially, the tank is empty. 1. Fill tank with solution (ethanol/A/B). 50°C (1 hour) Increase temperature of the feed from 20°C to 2. Reaction takes place isothermally at 50°C (4 hours, to give conversion of 50%) 3. Filtration of reaction solution to give product P (2 hours) 4. Drying with hot nitrogen gas followed by the removal of powder product (3…

A liquid is fed to a distillation column at 4 atm absolute pressure. Its composition as a mole fraction is: n-butane: 0.40, n-pentane: 0.25, n-hexane: 0.20, n-heptane: 0.15. Using the equilibrium distribution coefficients (K), find the temperature at which this liquid will begin to boil (bubble temperature). Calculate the concentration of the first vapor bubble formed.

Q.1) In the experiment, you wrap a piece of copper wire around your magnesium strip to suspend the magnesium inside the eudiometer. Why is copper wire a good choice for this task? Group of answer choices It conducts electricity very well It reacts strongly with the acid It does not react with the acid It is much heavier than Mg   Part B) A 45 mL sample of a dry gas is collected at 380 torr and 25 °C. Calculate the volume of the gas sample (in mL) at STP.   Part C)Using the data provided in Table 3 in the handout (also provided below), calculate the vapor pressure of water at 21.0 °C.

A continuous fractionating column is required to separate a binary mixture containing 0.20 mole fraction of A into a top product of 0.95 mole fraction A, and a bottom product containing 0.02 mole fraction A. The feed is liquid at its boiling point. The vapour leaving the column is condensed but not cooled, and the reflux ratio is 9:1. The relative volatility (a) remains constant at 1.85 and the vapour and liquid equilibrium data are in the form: α = y(1-x) x(1-y) Calculate: (a) the number of theoretical plates required; (b) the position of the feed plate;

Please help find Ccal. I was not sure what information is required so I have attached it below.
