Module 5

• Chemical reaction


  Concerned with breaking old bonds and creating new bonds.
• Reactant


  2 or more substances interacting with each other during chemical reaction
• Product


  Substance produced after chemical reaction
• Synthesis reaction(A+X = AX)


  2 or more substances combine to form a new compound
• Decomposition reaction (AX = A+X)


  It is a reverse reaction of the Synthesis reaction. It is a single compound that undergoes a chemical reaction and produces 2 or more substances.
• Single replacement reaction (A+BX = AX + B)


  One element replaced the similar element.
• Double replacement reaction (AX + BY = AY +BX)


  Two compounds exchange places to form two new compounds.
• Stoichoimetry


  Quantative relation between the number of moles of various products and reactants
• Chemical equation


  Shorthand method in writing a chemical reaction (chemical symbol and numbers represented their moles)
