1. Identify the five broad categories of toxins, and then provide an example of each that is found in the region where you live.
Your response should be at least three hundred words in length.
2. Discuss the beneficial applications of toxins, and provide an example of a specific toxin and its application.
3. Identify the factors that modify toxicity. Based on these factors, explain how exposure to the same concentration and duration of a toxin will affect a healthy, middle-aged male differently than a middle-aged female who smokes and has a suppressed immune system.
4. Toxicity can manifest in numerous ways. Describe at least four of these ways.
When M2S3(s) is heated in air, it is converted to MO2(s). A 4.500-g sample of M2S3(s) shows a decrease in mass of 0.209 g when it is heated in air. What is the average atomic mass of M.
Nickel and aluminum electrodes are utilized to build a galvanic cell. The standard reduction possible for the nickel(II) ion is -0.26 V as well as that of the aluminum(III) ion is -1.66 V.
The most probable radius is one measure of the size of an orbital. For s and p orbitals, how does the size depend on n.
The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted

What is the maxium amount of potassium sulfate that can be formed and what is the formula for the limiting reagent?
What volume of oxygen, in ml, would be produced at STP (0 degrees C and 1.00atom) by the decomposition of 3.428g of sodium chlorate, according to 2NaClO3(s) -> 2NaCl(s) + 3O2(g)
Question- A chemist with 4.0 moles of H2 and 4.0 moles of O2 in a 200.0 L container, and runs the combustion reaction very slowly. After 10.0 seconds there is 3.0 moles of H2. a) Write the balanced chemical reaction.
State a balanced chemical equation for the reaction that occurred. Keep in mind that halides are present in solution as sodium salts. Example sodium bromide
What is the pH of a 0.16 M solution of oxalic acid, H2C2O4. The Ka1,2 values of oxalic acid are 5.6 x 10-2 and 5.4 x 10-5. For a weak polyprotic acid, it is usually OK to assume the hydronium ion concentration, and hence the pH, results predominan..
