This unit introduces chemical reactions, the processes that create and transform matter. Learn about net ionic equations, reaction stoichiometry, titration, common reaction types, and more. Practice what you’ve learned and study for the AP Chemistry exam with 80 AP-aligned questions.
In this article, we'll look at how we can use the stoichiometric relationships contained in balanced chemical equations to determine amounts of substances consumed and produced in chemical reactions. Balanced equations and mole ratios.
The mole and Avogadro's number. One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles..
Transcript. Isotopes are atoms of the same element with different numbers of neutrons. Because they contain different numbers of neutrons, isotopes have different atomic masses. The average atomic mass of an element is calculated by taking the weighted average mass of the element's naturally occurring isotopes.
