CHEM 120 Week # 3 DQ 1 – Chemical Reactions and Equations (graded)

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 --- SF6 Starting with sulfur - there are eight on the left but only one on the right. Put 8 in front of SF6 S8 + F2 --- 8SF6 Now there are 48 fluorines on the right and only two on the left, so put 24 in front of F2 on the left S8 + 24F2 --- 8SF6 The chemical equation is now balanced!
