- Describe the process of catalytic cracking used in the petroleum refining industry Your answer must also include: · A balanced chemical equation, include physical states and reaction conditions. · Example of a product formed from catalytic cracking in petroleum refining, and its use. All sources need to be acknowledged using Harvard referencing please.Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 8 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000054 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL Do not include units with your answer.Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses.

How would C1q2 have to change to make 12 million tons the optimumreduction?Green Chemistry and Atom Economy The purposeful design of chemical products and processes that minimize the use of environmentally hazardous substances and the generation of waste is known as green chemistry. Green chemistry is a philosophical approach that is being applied to many areas of science and technology, and its practice is summarized by guidelines known as the “Twelve Principles of Green Chemistry” (see details at this website (http://openstaxcollege.org/l/16greenchem) ). One of the 12 principles is aimed specifically at maximizing the efficiency of processes for synthesizing chemical products. The atom economy of a process is a measureof this efficiency, defined as the percentage by mass of the final product of a synthesis relative to the masses of all the reactants used: atom economy = mass of product/mass of reactants × 100%Though the definition of atom economy at first glance appears very similar to that for percent yield, be aware that this property represents a…
