- Discuss simulation of combustion phenomena. Write down the effect of by-products emitting in combustion.The research group has recently focused on identifying the chemical properties of fluorocarbons, such as CF4 and C2F4. These fluorocarbons display a very different reactivity compared to hydrocarbons. Teflon (C2F4)n is a fluoropolymer. When Teflon is mixed with silica at high temperature, all solid decomposes into gases. Write down the reactions that can take place during the process and explain your reasoning.(a) In 20 or less of yourown words define the term “leachate”and describe how it forms. (b) Previous records had shown that to prevent acute toxicity to organisms, the maximum mass of CdSO4 that should be allowed into the landfill was determined to be 0.1 kg. This was calculated using a standard concentration of Cd in mg/L where the volume of the leachate pond was used as 500 000L. (i) Provide the name of the CdSO4 compound. State the oxidation number of Cd in this compound (ii) You need to ensure that the concentration used to determine the mass of Cd allowed in the landfill, meets the current regulatory standard. Assuming that previous calculations determined that all of the CdSO4 would be deposited in the leachate pond, what standard concentration of Cd in mg/L was used to determine the maximum mass of allowable CdSO4?

In particular, we will practice quantitative transfer and vacuum filtration. You will perform a precipitation reaction that involves preparing and combining solutions of sodium carbonate, Na2CO3, and calcium chloride, CaCl2. The balanced chemical equation for this reaction predicts the amount of precipitate that will be formed. Careful isolation, drying and weighing of the precipitate will confirm the calculations and the percent yield. Pre-Lab Questions 1. Define the term gravimetric analysis. Describe the procedure used in this activity, and identify two other common examples of gravimetric analysis.Imagine that you were the chief engineer for NASA's Apollo 13 mission to the moon. The air filter which they had been using is fully saturated and no longer works. The astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You remember that the astronauts have a container of 14.5 kg of sodium hydroxide on the ship. As a chemical engineer, you know that sodium hydroxide can be used to remove carbon dioxide from the air by producing sodium carbonate and dihydrogen monoxide. How many liters of carbon dioxide are cleaned by the amount of sodium hydroxide given in the problem? The astronauts have 3 days left before they land on earth. You know that there are 4 astronauts, and each astronaut emits roughly 700 grams of carbon dioxide (CO2) each day. • How many liters of CO2 are produced by the astronauts? • Is there enough NaOH for the astronauts to survive the rest of their trip? If the astronaut survived the trip, how much NaOH was left over? If the astronaut…
