We all face potential hazards in our workplaces and in our homes. Ideally we can eliminate or control many of these; however, if and when they occur, a Risk Assessment Plan is our best defense. To understand the preparation and use of such a plan, consider your past or present workplace or your home.
Writing the Paper
Type the electron configuration for the following ions according to the rules in your text. Use the format {He} 2s2 2p2 for carbon. Pay attention to the spaces.
Calculate the percent nickel in a compound for which a 11.6 mg sample required 1.38 mL of 0.010 M EDTA to reach the Murexide endpoint.
At a certain temperature, the equilibrium mixture of the reaction PCl5 (g) ? PCl3 + Cl2 (g) has PCl5 = 1.50 atm. PCl3 = 0.10 atm and PCl2 = 7.50 atm Calculate the value of Kp at this temperature
Problem- A metal pellet of 100.0 g at 95.0 degrees Celsius is dropped into 218 g of H2O at 23.8 degrees Celsius. if the metal pellet has a specific hear of 0.570 J/(g*degrees C) and the water has a specific heat of 4.184 J/(g*degrees C) what is th..
Determine the boiling point of water under pressure of 0.5 bar, given that the standard boiling point is 373 K as well as enthalpy of vaporization is 40.7 kJ/mol.
A cylindrical bar of copper 1.25 meters long and 2.22cm in diameter is initially at a temperature of 14°C. The bar is heated until it increases length by 1.77mm.
2,2-dibromo-3-methylpentane can be prepared by an addition reaction of excess HBr with an alkyne. Draw the structure of the alkyne, name it, and write the reaction
