56
oxidation
loss of electron
57
reduction
gain of electron
58
Redox (reduction-oxidation)
electrons are exchanged between atoms in the reacting compounds.
59
How do you find the molar mass of a compound
add up the atomic mass for each atom in the compound
60
Define Stoichiometry
The use of balanced chemical equations for quantifying the amount of materials in a given chemical reaction.
61
Why can’t a chemical equation be balanced by changing the subscripts of the reactants and / or products?
Because changing the subscripts means changing the identity of the chemicals
