reactions. The termcatalystappears in nonscientific discussions to refer to something that provokes or speeds significant change or action. Consider this example from the 2006 Associated Press article “Chernobyl cover-up a catalyst for glasnost”:For the Soviet Union, Chernobyl was a catalyst that forced the government into an unprecedented show of openness that paved the way for reforms leading to the Soviet collapse.Discuss how this scientific term […]

I want it by saturday 9 p.m . the sources should be peer reviewed and at least 5 . this paper has to be plagiarized free I have few sources already for this paper that I can give . PLEASE CITE PROPERLY. and discuss more chemistry in the paper. the topis I chose is postmortem toxicology.

read about costing systems and ratio and trend analysis. Applying the concepts in that you read about, pick a Company that you are familiar with and discuss the following:- The industry the Company operates in, the approximate size of the organization (revenue, number of employees, etc.) and the number of accounting staff- The type of information that would be relevant to management and how that […]

During a practical session, a good 2nd year Inorganic I student prepared a good quality alum double saltwith the general formula, M2SO4.M2(SO4)3.24H2O, where M is +1 and M is +3 cations. This wascarried out by weighing exactly 1.7418g of potassium sulphate, which was dissolved in 10mL distilledwater (dH2O). Similarly, 6.6644g of Al2(SO4)3.18H2O in the exact same fashion. The dissolved clearsolutions was mixed in a clean […]

200.0ml of a .800 M solution of sodium phosphate is reacted with excess lead acetate as shown below. How many grams of lead phosphate could be potentially be formed? Show your work.2 Na 3 PO 4 (aq) + 3 Pb(CH 3 COO) 2 (aq)= 6 NaCH3COO (aq) + Pb 3(PO4)2(s)

PLEASE HELP!!!Ariana and Alissa performed the synthesis of Ag2SO4. They measured a known mass of AgNO3, dissolved the salt in water and added this solution to an excess of aqueous K2SO4. They filtered the precipitate of silver sulfate, rinsed it with distilled water, and let it dry overnight. Next day, the mass of silver sulfate was measured. The collected results are shown in the Data […]
