☆☆☆☆☆The average atomic mass represents the weighted average of the masses of the isotopes of the element.
Stoichiometry is used to find the molar ratios between the reactants of a chemical reaction.
Stoichiometry relates moles of reactant to moles of product, so if you have the amount of reactant in the equation, you can calculate the amount of product produced.
Models are changed if they don't fit new data.
It minimizes sources of bias in the data.
Balancing redox reactions is different from balancing other reactions because both the number of atoms and the amount of charge must be balanced.
it loses mass
The reaction is nonspontaneous.
