☆☆☆☆☆Stoichiometry is used to find the molar ratios between the reactants of a chemical reaction.
The coefficients give the ratio of moles reactant to moles product.
The relative amount of mass an atom contributes to a molecule
It decreases when going down a group.
The sum of the voltages of the oxidatiin and reduction half-reactions is negative.
The element with the greater reduction potential is the one that is reduced.
A Spontaneous Redox Reaction

FeCl2(aq) + 2NaOH(aq) --> Fe(OH)2(s) + 2NaCl(aq)Thus 2 moles of sodium hydroxide react with every mole of iron(II) chloride.
Here we have only enough sodium hydroxide to react with 3 moles of iron(II) chloride.
Molarity is an indication for concentration.
