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 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...

Learning objectives • Explain the molecular structure of sugars and polysaccharides • Explain digestion and appreciate the complexity of the human body • Experiment with different foods and measure their impact on the blood sugar level Introduction Most people are familiar with carbohydrates, especially when it comes to what we eat. For example, to lose weight, some individuals adhere to “low-carb” diets. Athletes, in contrast, often “carbohydrate-load” before important compet...

6. (TCO 6) A gas at a temperature of 95 degrees C occupies a volume of 165 mL. Assuming constant pressure, determine the volume at 25 degrees C. Show your work. (Points : 5) Using Charles’ Law, ( V1/T1) = (V2/T2). First, convert temperature to KELVIN (T1 = t1 +273) Thus, T1 = 95 + 273 = 368. We have V1 (165 mL) & T2 = (25 + 273) = 298. V2 = (V1*T2)/T1 = (165 mL*298)/368 = 133.6 mL. 0 7 Short 16 7. (TCO 6) A sample of helium gas occupies 1021 mL at 719 mmHg. For a gas sample at constant tempera...
