Using Chemical Equations

Chemistry is really about reactions. Chemical change is a rearrangement of atoms  – as one or more substances change to new substances. Mole-to-mole relationships and mass calculations in particular provide a wealth of information to practicing chemists – and to chemistry students. Applying mathematical ratios, making practical use of scientific notation, and thoughtfully comparing both sides of an equation are important skills for chemistry students to master.

Background: Often, in math-related work, there are multiple “paths” for arriving at a correct answer.

  • Position A: Once having mastered one technique, no further techniques are needed or appropriate.
  • Position B: Multiple techniques, if available, are always helpful to learn.
