Learning Goals

To understand how to write and balance chemical equations

Investigate the law of conservation of mass

Law of Conservation of Mass

During any chemical equation, matter is neither created or destroyed. Mass is conserved from reactants to products in a closed system

Writing and Balancing Chemical Equations

💡

Types of Chemical Equations

• Word Equation
• Symbolic equation
• Molecular Equation

Example

• Coefficients - Changed to balance the equation
• Subscripts - Do not change

States of matter

s = Solid

l = Liquid

g = gas

aq = aqueous (dissolved in solution)
