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...

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...

Carbon electron configuration: 1s22s22p2 Carbon is the element that I have chosen for this post. Carbon has 4 valence electrons and they reside in n=2 shell, specifically the 2s and 2p orbitals. Carbon has 2 unpaired electrons from the 2p orbital. Carbon can form 4 covalent bonds. Carbon can participate in double and triple bonds because it can share 1, 2, or 3 pairs of electrons when bonding. The number of valence electrons in Carbon allows it to share the pairs of electrons with another Carbo...
