Aforwarded double effect evaporator is required to concentrate an orange com from o to 60% using steam at 170 kn/m (gauge) the food anters at 1 000 kahe at 303 and the forst effect is operated at 95 kn/m (gauge) additional information 1 cp is taken to be 4 18 kj/kg k 2 boiling point nise can be neglected 3 vi=v₂ 4 the overall heat transfer coefficients are as follows first effects 25 kw/m²k second effect= 25 kw/m²k 41 draw a diagram of this process, showing all streams and define the applicable operating conditions for each effect 4 2 calculate the required steam consumption (10) 43 calculate the steam economy (2) 44 determine the temperature and pressure in the second effect if the areas of each effect are equal

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
