  • What are the substances called formed in chemical reactions?
    products
  • A chemical reaction is the process of converting _____ to _____.
    reactants to products
  • How can we increase the speed of a collision?
    Increasing the temperature, splitting the substance into smaller pieces
  • What happenes in collision theory?
    chemical reactions are produced when the particles of the reactants collide with each other and are broken. The loose atoms rearrange themselves.
  • What is conserved in a chemical reaction?
    the atoms involved and the mass
  • In a chemcial reaction, what happens to the molecules of the reactants?
    they are destroyed
  • What is very important in determining weather or not a reaction occurs?
    The speed of particles
  • Name 3 chemcial reactions ( not in your book )
    hopefully good job
  • What happens when you pour acid on marble?
    You will see bubbles and during this reaction, the solid dissolves and CO2 is released
  • In the formation of hydrochloric acid, what has to happen in order to form the H-Cl molecule?
    the Cl-Cl molecules and the H-H molecules must first be broken
  • What happens to the atoms of the reactants in a chemical reaction?
    They regroup to form new molcules (but first they need to collide)
  • According to Antoine-Laurent Lavoisier, what stays the same?
    mass
  • A collsion is only effective if _____?
    the molecules collide at the right orientation and speed
  • What changes in a chemcial reaction?
    the chemical formula of the substance and the number of molecules (sometimes)
