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.
To begin, pick either question I, II, III, or IV from problem 1.
1.Determine the number of atoms for each element in the reactants.
2.Determine the number of atoms for each element in the products.
3.Given this determination, is the reaction balanced?
4.If the reaction is not balanced, what is the balanced chemical reaction?
