Option 1 A growing concern in agricultural and food chemistry is the presence of residues in food. We use many forms of organic chemicals in agriculture and food chemistry and there is growing concern as to how safe these materials are. Choose an organic chemical used in agricultural of food chemistry and report on the functional groups contained in your compound, the uses of the compound, and the safety of that compound. This research will require one or more outside sources. Ensure all citati...

Option 1: While we often think of radiation as dangerous, radioactive isotopes are widely used in the field of healthcare as well as in many other fields. For your initial post, choose a radioactive isotope used in healthcare or another field and report on how your isotope is used. Be sure to answer both of the following questions as part of your initial post: a. What type(s) of radioactive decay does your isotope undergo? b. How is your isotope used? Use at least one outside source and ci...

1. In your own words, describe what is occurring during the process of electron beta decay, explaining what is ejected from the unstable nucleus and focusing subatomic changes. (2 points for clear and accurate description). 2. Write balanced chemical reactions for the following: (1 point each, 4 points total) a. Cobolt-60 undergoes beta decay b. Americium-241 undergoes alpha decay c. Copper-60 undergoes positron emission d. Gallium-66 undergoes electron capture 3. Strontium-89 is an is...

Option 2: Radiation comes in many different forms. We are exposed to many types of radiation each day, not only form the technology that surrounds us, but also from natural sources. Choose a source of radiation that a peer has not already chosen and discuss each of the following as part of your initial post: a. Is the radiation ionizing or nonionizing? b. Is the radiation released from this source expected to be dangerous? Why or why not? c. Is this source of radiation natural or artificial?...

Initial Post Instructions While we often do not realize it, acidic and basic solutions are a part of our daily lives. Pick a solution in your home, work, or even outside (be sure to check the label to make sure that whatever you are measuring is nonhazardous and water based). Some possible solutions are shampoos, beverages, still water in your backyard, contact solution, etc. Research a compound or compounds found in your chosen solution, citing your sources in APA format and predict if the sol...

Your initial post in the discussion this week consists of two parts. First, choose a molecule used in healthcare, industry, or found in a natural source and discuss the importance of this molecule. Be sure to include at least one outside source and make sure to follow APA citation guidelines. The electron configuration of an atom determines the number of electrons available to participate in bonding with another atom. One method of depicting the valence electrons that an atom has is through the...

Solve these ideal gas law problems. Show all work for credit. 1. A gas occupies 250 mL at 739 mmHg. For a gas at constant temperature, determine the volume of gas at 514 mmHg. (1.5 points) 2. Use the molar volume of a gas, at STP, to determine the number of moles of CO2 in 4.00 L of CO2 gas. (1.5 points) 3. A sample of nitrogen (N2) has a volume of 50.0 L at a pressure of 2 ATM. What is the volume of gas at a pressure of 15 atm, if there is no change in temperature? (1.5 points) 4. A 0.6 L...

For your initial post pick a combination of one of the following molecules, one mass quantity, and one total solution volume from this table. You may not use the same combination as another student so be sure to read any existing peers postings before posting your own. Molecule Mass Volume NaCl 2 g 150 ml CaBr2 6 g 3 L Li3N 1 g 500 ml CaO 7 g 14 L For example, one possible combination would be 2 grams of NaCl in 500 ml of solution.Then, give each of the following for your uni...
