... All AP equations "work". In each case, a reaction will occur. These equations need to be written in net ionic form. All spectator ions must be left out and all ions must be written in ionic form. All molecular substances and insoluble compounds must be written together (not ionized!). Know your sol ...

... Note: We could’ve multiplied the second equation by (-4) and eliminated the x-terms. Note also: When making the coefficients equal but opposite, it is wise to find the least common multiple for the two coefficients. This will give us smaller numbers to deal with. Now, we add our new equation to the ...
