Understanding the definitions and terminologies associated with environmental toxicology is very important to a public health professional's basic environmental health education. In this assignment, you will research environmental toxicology and write a paper titled "The Toxicity of a Chemical."
Address the following in your paper:
According to the following balanced reaction, how many moles of NO are formed from 8.44 moles of NO2 if there is plenty of water present? 3 NO2(g) + H2O(l) = 2 HNO3(aq) + NO(g)
What is the mole fraction of acetone, C3H6O, in the vapor phase from a solution consisting of a mixture of acetone and ethyl acetate, CH3COOCH2CH3, at 30.00 °C, if the total pressure above the solution is 184.6 torr?
Quinine emits fluorescence at the wavelength of 347 nm. An unknown quinine solution gave fluorescence reading of 400 (after background subtraction) at the 347nm.
Calculate the concentration of malonate ion (C3H2O4 2-) in a 0.200 M solution of malonic acid (C3H4O4). The malonic acid, Ka1 = 1.4 x10^(-3), Ka2 = 2.0 x 10^(-6)
The haber process is a method in which ammonia can be produced from nitrogen gas and hydrogen gas. If nitrogen gas at 200 atm and hydrogen gas at 500 atm are combined at 500?C in a 50.0L vessel: determine the amount of ammonia that would be produc..
What are the advantages and disadvantages of using simple distillation vs fractional distillation methods. (in terms of gas chromatography)
Write the half-reactions that occur in the two electrode compartments. (Type your answer using the format [Ag] for Ag and Ag for Ag. Also, the first box gets the coefficient)
What is the characteristic of matter that causes it to expand when the temperature increases and contract when the temperature decreases?
Balance the equation and calssify the reactions. if an oxidation reduction occurs write the half reactions and identify the oxidizing and reducing agents.
For detection using Fluozin-3, what is the excitation wavelength that should be used. For Zincon detection of zinc and copper, what pH range agent do, and why would it be useful for metal detection
Find the PH of the final mixture when a solution containing two weak acids, i.e., 4mM ethylene (Kb1=4.72x10-4) and 2mM ethylene (Kb2=10-4) is titrated with twice its volume of 3mM HCL
What volume of a 0.33 M Mg(NO_3)_2 solution contains 97 g of Mg(NO_3)_2?
