What is the basic unit of chemistry
How is stoichiometry used to calculate the amount of product produced
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.
How are models affected by new evidence
Models are changed if they don't fit new data.
What happens at the cathode in an electrolytic cell
Reduction occurs at the cathode in an electrolytic cell.

Electricity acts in ways similar to ice, which is a solid.
Why is the average atomic mass used when calculating grams of a substance
the elements in the substance are mixtures of their isotopes
Which metal gets coated during electroplating
The cathode gets coated during electroplating.
What characteristics indicates that an atom is unstable
by creating very strong bonds
What is the oxidation half-reaction for Mg s plus ZnCl2 aq --- MgCl2 aq plus Zn s
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus
ZnCl2 aq.
All life on earth is ultimately dependent on what
Reduction occurs at which electrode
The electrode that removes ions from solution
