a) Which reactant is in excess?

b) Calculate the mass of product formed.

3. Arcylonitrile, C3H3N, is the starting material for the production of a kind of synthetic fibre. It can be made from propylene, C3H6, by reaction with nitric oxide, NO, as follows: 4 C3H6(s) + 6 NO(g) → 4 C3H3N(s) + 6 H2O(l) + N2(g)

What mass of C3H3N can be made when 21.6 g of C3H6 react with 21.6 g of nitric oxide? Identify the limiting reactant in the reaction.

Assignment 3

Procedural Text: Database Search

TOPIC- WATER POLLUTION

2) Goal [1 mark]

• State what will happen at the end

3) Series of Steps [8 marks]

• List what needs to be done to attain your goal in logical order.
• Be sure to keep instructions specific, short, simple and to the point.
• Use formal language
• Use present tense

4) Locate/identify 3 different resources [6 marks]

• (Example) a newspaper article, journal article and a documentary.
• Be sure that all sources are references in adherence to APA formatting
• Be sure that the sources you identify actually relate to your topic!

5) Strategically placed images [3 marks]

• If you find that something needs further elaboration, a good idea is to insert a screenshot of what you are referring to!

6) Conclusion [3 marks]

• Your conclusion should be a short paragraph that includes the following key points:
  • Reflection on any challenges you encountered
  • Any tips or advice you can offer to make the database search easier and more effective for your audience

A process for the production of 1,3-butadiene results from the catalytic dehydrogenation at atmospheric pressure of 1-butene according to the reaction

C4H8(g) C4H6(g) + H2(g)

To suppress side reactions, the 1-butene feed stream is diluted with steam in the ratio of 10 moles of steam per mole of 1-butene. The reaction is carried out isothermally at 525oC, and at this temperature 33% of the 1-butene is converted to 1,3-butadiene. How much heat is transferred to the reactor per mole of entering 1- butene?

Describe an ecosystem that you are familiar with. Include examples of abiotic and biotic factors, producers, consumers, and decomposers. Describe at least two ways that humans have impacted this ecosystem, or similar ecosystems. What is the effect on biodiversity?

Reactant A decomposes by three simultaneous reactions to form three products, one that is desired, B, and two that are undesired, X and Y. These gas-phase reactions, along with the rate laws, are as follows. (40pts) 1) A→X -r1A = rX= k1 = 0.0001 mol dm-3 sec-1 2) A→B -r2A = rB = k2 CA 2 = (0.0015 s-1 ) CA 2 3) A→Y -r3A=rY=k3 = 0.008 dm3 mol-1 sec-1 The specific reaction rates are given at 300 K and the activation energies for reactions (1), (2), and (3) are E1 = 10,000 kcal/mole, E2 = 12,000 kcal/mole, and E3 = 20,000 kcal/mole. (a) How, and under what conditions (e.g., reactor type(s), temperature, concentrations), should the reaction be carried out to maximize the selectivity of species B for an entering concentration of species A of 0.4 M and a volumetric flow rate of 2.0 dm3 /s? (b) Design the suitable type of reactor assuming there is no pressure drop.

What is the most important think you learned about Green Buildings, Sprawl, and Sustainability Initiatives from the textbook? like a summary of it.

A 5,000 mol/h fuel is fed to a furnace and burned with excess air. The fuel contains 80.0 mole % carbon (C), 15.0 mole % hydrogen (H) and the remainder sulphur (S). The ratio of feed fuel to feed air is 1:7. The selectivity of carbon dioxide (CO2) to carbon monoxide (CO) production is 12. The conversion of fuel in this process is only 80%. One of the components in the flue gas is sulphur dioxide (SO2).

(a) Write all equations that involved in this combustion process.
(b) Draw and label the process completely.
(c) Using Atomic Species Balance method, determine the molar flow rates (mol/h) of all components in the product. stream.                                                                             
(d) Determine the percentage of excess air in this process.
