AC-HPAT Chemistry Study Guide 2023 with complete solution double-displacement reaction A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products Precipitate precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid fro...

What was originally considered to be the genetic material? Why? Correct Answer-Proteins were considered to be the genetic material because they were inherently more complex than DNA. Avery, McCarty, MacLeod experiment Correct Answer-First, think about Griffith's experiment and how even heat killed strains of S. pneumococcus still led to death of non pathogenic cells ⁃ Process: Grind up virulent cells, isolate the active genetic material ('transforming principle') and infuse it into non...

How do nuclear gauges work? Why does so much care need to be taken when using them? - AnswerNuclear gauges use the interaction of radiation with matter to measure the density and moisture of material. Radiation sources within each gauge transmit radiation through the test material. Detectors contained in the gauge measure the radiation that is scattered by the test material or that passes through it. By calculating the percentage of radiation that reaches the detectors, the gauge can determi...

CHEM120 Week 6 Discussion: Radiation – Radioactive Isotope: Cobalt-60 (Option 1) Option 1 Cobalt-60 a. What type(s) of radioactive decay does your isotope undergo? Radioactive decay occurs when an unstable nucleus changes into a stable nucleus by emitting radiation. The cobalt-60 isotope undergoes a beta decay and produces gamma rays as it decays. The half-life for cobalt-60 is 5.27 years. This is how long the decaying process takes to get to Nickel-59, a more stable isotope ("Cancer Therapy,...

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...
