Formaldehyde (hcho is produced commercially by the formox process. a silver catalyst enables a partial oxidation of methanol (reaction 1) as well as the dehydrogenation of methanol (reaction 2) both of which produce formaldehyde. air is used for the supply of oxygen. two side reactions (reactions 3 and 4) occur in the reactor and produce co and formic acid (hcooh) respectively. the overall mass balance for the process is given in table 1 below. (hint: use an overall system boundary that hides the internal streams.) reaction 1 reaction 2 reaction 3: reaction 4 ch3oh → hcho + h2 choi i + (); -* 2112() + co process gas 12 purge absorber absorber 2 water figure 1: the formox process. table i: component flow rates for feeds and product streams. 20 strean tal (kmol/h) methanol (kmol/h) oxygen (kmol/h) nitrogen (kmol/h) formaldehyde (kmol/h) water (kmol/h) formic acid (kmol/h hydrogen (kmol/h) co (kmol/h) 42 50.49 40 61.32 1.96 8.82 33.18 - 33.18 0.2 24 0.14 1.25 0.59 16.99 33.38 0.12 40 a) use the mass balance table and the flow sheet to get an idea of what is happening in the process. b) calculate the extents of the four reactions. the following basic exercises involve the ammonia reaction: 2. part a. hydrogen and nitrogen are mixed in stoichiometric proportion and fed to an ammonia reactor the %conversion is 15% and a production rate of 20 kmol/h of ammonia is required. a) calculate: i. the feed rate to the reactor. i. the flow rate and composition of the reactor product. b) redo question (a) for the situation i. the feed mixture has a 10% excess of hydrogen but the flow rate of h2 is the same as in a) chmt1002: august 2017 ii. as in b() but the % conversion of hydrogen specifically is 15%, iii. what is the conversion of n2 for bii)?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
