Chapter 8: Lesson 2
Chemical Equations
![Page 2: Chapter 8: Lesson 2 Chemical Equations.](https://reader034.fdocuments.in/reader034/viewer/2022050807/5a4d1b8b7f8b9ab0599bee76/html5/thumbnails/2.jpg)
+Elements, Compounds, and Molecules
![Page 3: Chapter 8: Lesson 2 Chemical Equations.](https://reader034.fdocuments.in/reader034/viewer/2022050807/5a4d1b8b7f8b9ab0599bee76/html5/thumbnails/3.jpg)
+Elements
• Consist of only 1 type of element
• Symbols for the elements are found on the periodic table

+Diatomic Molecules
• Neutral particles in which elements share electrons
Diatomic = “two” atoms• These molecules have
two atoms of the same element.
• Remember: HNOFClBrI• H2, N2, O2, F2, Cl2, Br2, I2

+Compounds
Compounds are composed of 2 or more different atoms.
H2O: water is a covalent compound
NaCl: salt is an ionic compound {Formula Unit}

+Law of Conservation of Mass
Mass Before = Mass After Mass of reactants = Mass of Products
