Chemical reactions

  1. 1. Denisse SanchezDestiney Haynes
  2. 2.  A chemical reaction is the process by the atoms of one or more substances are rearranged to form different substances Reactants and products make up the chemical reaction A chemical equation is a statement that uses chemical formulas to show the identities and relative amounts of the substances involved in a chemical reaction A coefficient in a chemical equation is the number written in front of a reactant or product
  3. 3.  Synthesis: a chemical reaction in which two or more substances react to produce a single product Combustion: oxygen combines with a substance and releases energy in the form of heat and light Decomposition: one in which a single compound breaks down into two or more elements or new compounds
  4. 4.  SingleReplacement: a reaction in which the atoms of one element replace the atoms of another element in a compound Double Replacement: the final type of replacement reaction, which involves an exchange of ions between two compounds
  5. 5.  Anaqueous solution contains one or more substances called solutes dissolved in the water. Water is the solvent- the most plentiful substance in the solution.
  6. 6.  Atoms cannot be created or destroyed All the atoms we start with we must end up with A balanced equation has the same number of each element on both sides of the equation
  7. 7. 1. Write the correct formula for all the reactants and product2. Count the number of atoms of each type appearing on both sides3. Balance the elements one at a time by adding coefficients4. Start with the highest subscript5. Save hydrogen and oxygen for last6. Check to make sure it is balanced
  8. 8. NEVER change a subscript to balance an equation!!!!!!!! NEVER change a formula!!!NEVER put a coefficient in the middle of a formula!!!!
