Storyboard Text

  • A Chemical Reaction is a process that use rearrangement of molecules to form a substance.
  • In a chemical reaction, the atoms and molecules made by the reaction. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants brakes and the atoms are rearrange to make new bonds to make the products.
  • In a chemical equation, the reactants are written on the left, and the products are written on the right. The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
  • A chemical equation is a short expression of a chemical reaction. There are 2 parts to a chemical equation. The reactants are the elements or compounds on the left side of the arrow and the right of the arrow are the products.
  • The chemical equation needs to be balanced so that it follows the law of conservation of mass, witch means it can't be destroyed. A balanced chemical equation happens when the number of the different atoms of elements in the reactants side is the same as the products side.
  • Increasing temperature speeds up a reaction because there are more accident and the accident have higher energy. Chemical reactions that speed up the reactions by increasing the number of successful accidents. The chemical reactions are not used up in a reaction. Smaller particles have a larger effect.
