In polymеr form, thе doublе bond bеtwееn thе carbons is lost & a chain is formеd bеtwееn rеpеating units of two carbons, еach bondеd to two h...

CHEM-120 Week # 7 DQ 2 – Nucleic Acid Structure and Flow of Genetic Information (graded) In the news, we often hear examples of how DNA or the transfer of genetic information impacted someone’s life. Examples range from DNA fingerprinting to genetically engineered organisms to an individual with a genetic disease. In each of these scenarios, the structure of nucleic acids and the flow of genetic information through mRNA to protein are involved. Describe an example of the how the structu...

CHEM 120 Week # 4 DQ 1 – Gases (graded) Matter exists in three different states: solid, liquid, & gas. Depending upon its physical properties, matter will be found in one of these states at ambient temperature & pressure. Describe a situation where a substance changed between the solid & liquid states or between liquid & gas states? Can you describe an example of when a substance changed between the gas & solid states? Let’s see how many different examples we can describe. One...

3rd post I use apple cider vinegar for multitude of things in my home, from cleaning my produce, or even taking a shot of it in morning to help boot my metabolism. It is an essential product in my household. The apple cider vinegar I use is already diluted by the manufacturer to 5% acidity in a 32 FL OZ (946 ml) bottle. Vinegar is a naturally-occurring liquid that contains many chemicals, so it can’t just be written in a simple formula. It has Two main Chemical formulas H2O (water) C...

CHEM 120 Week # 3 DQ 1 – Chemical Reactions and Equations (graded) Understanding chemical reactions and the information that is available in a balanced chemical reaction is an important concept in chemistry. By working with a variety of problems, one will become comfortable with the concepts and be able to apply these concepts. The first concept that we will discuss is balancing chemical reactions. Look at the Self-Assessment Questions on page 129 in your textbook. S8 + F2 ---> S...

Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Symbol: O Atomic number: 8 Atomic mass: 15.999 which also can be around up to 16 Number of Protons = the number of Electrons which is 8 In order to know the number of neutrons Subtract number of protons from the atomic mass 16 – 8 = 8 ...

CHEM 120 Week # 1 DQ 1 – Scientific Method and Calculations Let’s explore the scientific method. Here is the situation: We are planting a garden. We have a variety of bulbs and 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. 1) What are some of the characteristics that we want to obser...
