1. Formaldehyde can be produced by oxidation of C2H4 and the following reaction may occur.

C2H4 + ½ O2  C2H4O C2H4 + 3O2  2CO2 + 2H2O

Using molecular balance method. Equimolar quantity of C2H4 and O2 was used and the product gas analysis shows 28.57% C2H4O, 11.43% CO2, 11.43% H2O, 22.86% C2H4 and 25.71 % O2. Calculate the % conversion of C2H4 and % Yield of C2H4O.

Example 2.7 Gas Phase Reaction
Gas phase reaction is taking place in a continuous reactor. Stoicliioinetric proportions of

CO2 and H2 are fed to tile reactor at +00o C. The reaction proceeds to 80'a completion.
Given I mol of carbon dioxide, estimate the I)eat tllat dust be provided or removed, if tile
gas exit steams are to be kept at 500'C. Perform the energy balance using tile lleat of
reaction method at two reference teniperatuies (500'C and 25'C) and the beat of

formation method

C. Gravitational pull of the moon

D. Earth's Axial Tilt

The air at the entrance to a grain dryer is 40.0 ° C and 20.0% RH. The debit

is 300.0 L / s. The dryer extracts 7,000 kg / h of grain water. The air temperature at

dryer outlet is 30.0 ° C. What is the relative humidity (%) of the air leaving the dryer?

The total pressure everywhere is 101.3 kPa.

Yes debit means flowrate of air entering.

What is the size of cough and sneezing droplets and how far they can travel? (try to calculate the distance and give reference of scientific studies only. You can use video or images to explain your answer wherever needed)

find solution of the following question:

a) propose a strategy to form the strongest Al 2024, and List two main drawbacks of such a material.

b) Precipitation hardening ( increases/decreases ) the yield strength of materials

In a static bed, how can we describe the forces responsible for the initiation or non-initiation of grain or sediment movement from a static bed.

One way to makebromine is to react HBr and O2to form Br2and H2O. Air (21 mole% O2, 79 mole% N2)is fed to provide 35% excess oxygen, and the fractional conversion to HBr is 85%. (a)Calculate the mole fractions of the product stream components, using atomic species balances in your calculation.(b)Repeat (a) but use the extent of reaction equations instead.

1.In an experimental cracking of octane (C8H18), the product has the following composition: 19.5% C3H8, 59.4% C4H10, and 21.1% C5H12. Cracking is the process of reacting long hydrocarbon chains with hydrogen gas to produce hydrocarbons of shorter lengths. Determine the molar ratio of hydrogen gas consumed to octane reacted.
