☆☆☆☆☆The average atomic mass represents the weighted average of the masses of the isotopes of the element.
16.0 lbs = 7,257 g of O2
Oxygen exists in the gas form as 02
7,257g O2 * 1 mol O2/ 32 g * 2 mol O / 1 mol O2 * 6.022x10^23 atoms/mol
= 2.73E26 atoms of O
Stoichiometry is used to find the molar ratios between the reactants of a chemical reaction.
a salt bridge
the gold electrode
reduction happens at the cathode
Oxidation happens at the anode
it loses mass
Reduction occurs at the cathode in an electrolytic cell.
The cathode
Electrochemistry
A battery containing a spontaneous redox reaction
The cathode gets coated during electroplating.
The electrode that removes ions from solution
electronegativity
In this case the yield is 77,27 %.
Magnetism can create electricity, and electricity can create magnetism.
