in a chemical formula tell how many atoms of an element are present in that compund basic unit
in a balanced equations tell how many units of each reactant are needed and how mant units of each product are made
law of conservation of atoms
the atoms present in the reactants are rearranged to form the products. atoms are not lost or gained during a reaction.
temperature surface area stirring increasing and decreasing the concentration of the reactants catalysts
factors affecting reaction rate
increasing heat causes an increase in the average kinetic energy of the reactants. causing more motion. more motion = more collisions
can be increased by gridding and chopping. the more of this the faster the reaction will happen
