Q5 - Anthropogenic Carbon Flux

What is the total anthropogenic flux to the atmosphere, including both fossil fuels and land use, in PgC? We're looking for the flux to the atmosphere, not the net flux (don't subtract out red fluxes from atmosphere to land or ocean).

The feed mixture is fed into a continuous distillation column as liquid at its bubble point . the column operates at ambient conditions to achieve a 99.2% recovery of component ethane in the distillate product and 95.7% recovery of propane in the bottoms product.

1. determine the light key (LK) and heavy key (HK) components for the system

2. complete the material balance over the distillation column and calculate the mole fraction of each component in the feed, distillate and bottoms stream

1. Your Company is contemplating investing in the Aggregate Mining industry in Ontario or any canadian province. Your supervisor has asked you to prepare a report (3 pages minimum, 5 pages maximum excluding images) including pictures and references, defining and explaining the use, extraction methods and the contribution of Aggregate mining to the Ontario economy . Hint: You may want to visit the Ontario web sites: (15 points)

please type your answer, Please do not write on the paper and post it

Water flowing at a rate of 100 Kg/min at 100 ^oC and 20 bars is heated at constant pressure to 400 ^oC. What are the initial and final phases of the water (subcooled liquid, saturated liquid, saturated steam, or superheated steam)? (saturation temperature of water at 20 bars is 212.4 ^oC).

It is common practice to dump strong acids and bases (nitric, sulfuric, NaOH ect.) down the drain into the water supply after dilution and mixing with sodium bicarbonate. Are sanitary plants able to filter out 100% of these chemicals before being put back into circulation or the enviornment? What are the possible health and enviornmental effects of this practice?

write a summary of the current cloud cover in north america. Include date and time of the image in your report.

Initial Post:

Herbert Hoover and Franklin D. Roosevelt had very different attitudes about government and approaches to deal with the Great Depression. Describe each president's approach to the economic crisis, with examples from the speeches of President Hoover versus President Roosevelt.

Analyze the two approaches and consider:

• What was the long term impact of each President's actions?
• How did these different approaches change what Americans felt the government should be doing for them?

Your initial post should:

• Be 300-400 words in length.
• Describe each President's approach and consider the impact.
• Give at least one example from each President's speech.
• Use formal academic language, including MLA format citations- both parenthetical citations in your post, and full citations at the end. Please refer to the class Writing Guidelines and/or the MLA citation resources for a refresher.
