Ch 11: MTTC Physical Science: Stoichiometry

About This Chapter

In this chapter, get reacquainted with stoichiometry as you determine how to find compound ratios in chemistry. To improve your chances of passing the MTTC Physical Science exam, use the lesson transcripts to commit key equations to memory.

MTTC Physical Science: Stoichiometry - Chapter Summary

When it comes to stoichiometry, there are many steps, rules, and symbols to remember, but these lessons can get your memory on track. Prepare for solving stoichiometric equations on the MTTC Physical Science exam by delving into these topics:

  • Balancing chemical equations
  • Exergonic and endergonic reactions
  • Mass-to-mass and mole-to-mole calculations
  • Calculating reactants
  • Hydrates and precipitation reactions
  • The law of conservation of mass
  • Chemical nomenclature

Stoichiometry can prove difficult, since there are so many steps involved and calculation processes to perform. This chapter can give you the type of rundown you'll need to put you in a better position for the MTTC Physical Science exam. First of all, you can't teach a subject like this without using examples, and our instructors tend to use very relevant and familiar examples. If you didn't catch everything the first time through a lesson, you can watch it again until you get it. You can also read the transcripts to see the vocabulary word definitions as well as the chemical formulas.
