A petrochemical plant in Island C produces formaldehyde (CH2O) industrially by the

catalytic oxidation of methanol (CH3OH). The following is the chemical reaction:

CH3OH + ½O2 → CH2O + H2O --- (1)

Unfortunately, a significant portion of the formaldehyde will react with oxygen to produce CO

and H2O. The following is the side reaction:

CH2O + ½O2 → CO + H2O --- (2)

Assume twice the stoichiometric amount of air needed for oxidation (all chemical reactions) is

fed to the reactor. The conversion of methanol is 90% in the reactor. The outlet stream of the

reactor was analysed and found to be 150 kg/hr of formaldehyde, 30 kg/hr of CO and other

components.(i) Determine the mass flowrate (kg/hr) of Stream A. (ii) Determine the molar flowrate (kg-moles/hr) of Stream B (iii) Determine the mass flowrate (kg/hr) of water in the outlet stream.

Can somebody help me with that

On the position time curve, if the slope of a tangent at a point is positive, that means:
A: The object is moving backward
B: The object is not moving
C: The object is moving forward

In a certain week, a production schedule for a certain department shows the following parts being produced: 540 parts of type A, 1200 parts of type B, 490 parts of type C, and 780 parts of type D. The respective production times for these parts are the following: TpA = 5.28 min, TpB = 2.86 min, TpC = 4.65 min, and TpD = 3.22 min. Determine the workload for this department in hours per week.
