on 12 You are the project manager of an environmental company that was hired to cleanup a historical arsenic contamination site. Soil sampling results indicated the area impacted with arsenic above action levels is 30 feet by 55 feet. The depth of the arsenic plume is three feet below ground surface. The land owner wanted to clean this site for future development. Using your textbook, answer the questions below to help you prepare a cost estimate for this portion of the project. Your solutions and any assumptions to justify your estimate must be shown. What is the chemical symbol of arsenic, and what group/family does it belong to? Solve for the minimum volume of soil that will be excavated in cubic yards? If each dump truck can transport 18 cubic yards, determine how many dump trucks loads will be transported? For calculation purposes, add a 15% ?fluff factor? (add to the volume that will be transported). If the bulk density of soil is 1350 kg/m3 (84.3 lb/ft3), solve for the weight of the soil that will be transported to a disposal site in kilograms? Your total response to parts a-d must be at least 200 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced. Paraphrased and/or quoted material must have accompanying citations in APA format. book: Meyer, E. (2014).

If a second-period diatomic molecule has 4 electrons in its valence shell (total of 2s and 2p electrons), what is the predicted bond order of the molecule
Quantum numbers are used to uniquely identify an electron in an atom. The Pauli exclusion principle states that no two electrons in an atom may have the same set of four quantum numbers

Why is acetanilide more reactive than methyl benzoate in a competetive nitration
In BPTI the phenylalanine has five aromatic resonances of equal intensity. However after incubation in 6 M urea the same Phe has three resonances, one of which has half the integrated area of each of the others which have the same area.
A 6.50 x 10^-5 M solution of potassium permanganate has a percent transmittance of 27.3% when measured in a 1.15-cm cell at a wavelength of 525 nm.
