- 4.131. Compute the heat of reaction at 600 K for the following reaction: S(l) + O2(g) SO2(g)arrow_forward(4) Liquid-liquid extraction(also known as solvent extraction) involves the separation of theconstituents (solutes)of a liquid solution by contact with another insoluble liquid. Solutes are separated based on their different solubilities in different liquids. Separation is achieved when the substances constituting the original solution is transferred from the original solution to theother liquid solution. (a)A solution of10per cent acetaldehyde in toluene is to be extracted with water in a five stage co-current unit. If 25 kg water/100 kg feed is used, what is the mass of acetaldehyde extracted and the final concentration? The equilibrium relation is expressed as:(kg acetaldehyde/kg water) = 2.20 (kg acetaldehyde/kg toluene)arrow_forwardA chemical engineer is studying the following reaction: BF3(aq)+NH3(aq) → BF3NH3(aq) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 1.1. The engineer charges ("fills") three reaction vessels with boron trifluoride and ammonia, and lets the reaction begin. She then measures the composition of the mixture inside each vessel from time to time. Her first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should expect next time she measures the compositions. reaction vessel compound concentration expected change in concentration BF 3 0.64 M O f increase OI decrease O (no change) A NH, 0.90 M O f increase OI decrease O (no change) BF;NH; 0.63 M O f increase O! decrease (no change) BF3 0.84 M O f increase O! decrease O (no change) В NH, 1.19 M O f increase OI decrease O (no change) BF;NH, 1.09 M O 1 increase OI decrease (no change) BF3 0.38 M O t increase OI decrease O (no change) NH, 0.64 M O t…arrow_forward
- Balance the following equation according to the half-reaction method: H2S (g) + Hg22+ (aq) -> Hg (l) + S (s) *in acid The answer the book gives is: H2S + Hg22+ + 2H20 -> 2Hg + S + 2H3O+arrow_forwardAn electron in a hydrogen atom is excited from the ground state to the n = 3 state. True or false? (i) The n = 3 state is the first excited state. (ii) It takes more energy to ionize (remove) the electron from n = 3 than from the ground state. (iii) The electron is farther from the nucleus (on average) in n = 3 than in the ground %3D state. (iv) The wavelength of light emitted when the electron drops from n = 3 to n = 1 is longer than that from n = 3 to n = 2.arrow_forwardBalance the following redox reaction in an acidic solution: UO22+(aq)+Zn(s)->U4+(aq)+Zn2+(aq)arrow_forward
