Chem 120 week 1 dq 2 Study guides, Class notes & Summaries

CHEM 120 Week 6 DQ 1 – Polymers (graded) What do you have in your home that is constructed from a synthetic polymer? Identify the type of polymer and its monomer. List THREE examples each CHEM-120 Week 6 DQ 2 – Nuclear Chemistry and Energy (graded) Radiation can be found in different forms. Electromagnetic radiation is something that we use every day. Ionizing radiation can cause damage to living tissue. Take a look around you. Describe an example of a way in which you are impacted by radia...

CHEM-120 Week # 1 DQ 2 – Atoms and Atomic Structure There are a number of elements (minerals) that are important to human nutrition. These include sodium, potassium, calcium, chloride, magnesium, iron, copper, manganese, iodine, molybdenum, and selenium. There are many additional elements that are useful in industry. Using the periodic table of elements, pick one of these elements and determine the number of protons, neutrons, and electrons found in this atom. Be sure to check that you a...

CHEM 120 Week # 1 DQ 1 – Scientific Method and Calculations CHEM120 Week 1 Scientific Method & Calculations Let’s explore the scientific method. Here is the situation: We are planting a garden. We have a variety of bulbs & potted plants. We do not have any directions on how or when to plant each of these items. We do not have any gardening books, magazines, or access to the Internet (Oh, the horror!). We need to observe a number of characteristics for these plants. What are some...

CHEM 120 Week # 2 DQ 1 – Chemical Names (graded)

CHEM 120 Week 2 DQ 1 – Chemical Names (graded) Sulfates, sulfites, nitrates, nitrites—how does one keep all of these similar but different names straight?

CHEM 120 Week # 2 DQ 1 – Chemical Names (graded) Sulfates, sulfites, nitrates, nitrites—how does one keep all of these similar but different names straight? Let’s begin this discussion by talking about the naming of different compounds. Why would it be important to make sure that you know which compound is associated with which name? To apply these concepts, look at problems 18 & 22 on page 122. Choose one part of the problem, & provide your answer. Check out the following explan...

CHEM-120 Week # 6 DQ 2 – Nuclear Chemistry and Energy (graded) Radiation can be found in different forms. Electromagnetic radiation is something that we use every day. Ionizing radiation can cause damage to living tissue. Take a look around you. Describe an example of a way in which you are impacted by radiation. Is this a type of ionizing radiation? What is the source of this radiation? Let’s see how many different examples can be identified. Answеr: Thе hеalth risks associatеd w...
