Press the Right Arrow Button to Advance through the Presentation! SPI 0807.9.10 Reactants & Products Notes • Look at the chemical equation below. • Identify the reactants and products (see page 340) Here are the reactants Here are the products C + O2 CO2
SPI 0807.9.10 Reactants & Products Notes • Contrast reactants and products (how are they different?) • Reactants-are the starting materials in a chemical reaction • Remember: the arrow ALWAYS points away from the reactants! Here are the reactants C + O2 CO2
SPI 0807.9.10 Reactants & Products Notes • Contrast reactants and products (how are they different?) • Products- are the substances formed/produced in a chemical reaction • Remember: the arrow ALWAYS points towards the products! Here are the products C + O2 CO2
SPI 0807.9.10 Reactants & Products Notes • 2 parts of chemical equations • (1) reactants • (2) products • Reactants:are the things you are combining together…the things you start with in a chemical reaction • Products: are the things that you produce in a chemical reaction… the things you end up with • Example: 2H2 + O2 2H2O Products (water) Reactants (H & O)
SPI 0807.9.10 Reactants & Products SPI 0807.9.11 Law of Conservation of Mass Notes Key Topic Chemical Equations Chemical formulas combined together = chemical equations Examples: Equation:2H2 + O2 2H2O Equation:2Na + Cl2 2 NaCl
Quick Review SPI 0807.9.10 Reactants & Products • 2H2 + O2 2H2O Identify the reactants in this equation. Reminder: The arrow always points away from the reactants! 2H2 and O2 …or you could simply indentify the reactants as H (hydrogen) and O (oxygen)
Quick Review SPI 0807.9.10 Reactants & Products • N2 + 3H2 2NH3 Identify the product in this equation. Reminder: The arrow always points towards the product(s)! 2NH3 …or you could simply indentify the product as NH3(ammonia)
Quick Review SPI 0807.9.10 Reactants & Products • 2NaCl 2Na + Cl2 Identify the reactants in this equation. Reminder: The arrow always points away from the reactants! 2Naand Cl2 …or you could simply indentify the reactants as Na (sodium) and Cl (chlorine)
Quick Review SPI 0807.9.10 Reactants & Products • Sn + 2H2O SnO2 + 2H2 Identify the products in this equation. Reminder: The arrow always points towards the products! Snand 2H2O …or you could simply indentify the products as Sn (tin) and H2O (water)
