LET’S GET STARTED!
Set up an equation.
Ask Mr. Kirk for help.
Give up
OPPS!
NO DON’T GIVE UP!
CORRECT! WOW YOU’RE SMART
2KLCO3→2KCL+3O2 O2+KCLO3→KCL KLCO3→KCL+O2
OPPS!
NICE JOB!
Place the given amount over 1.
Multiply the given amount by
how many elements you
have.
Divide by the amount of
moles.
SORRY
MAYBE YOU SHOULD PAY ATTENTION
AWESOME!
Convert into moles, by
using the gfm of KCLO3.
Convert into liters.
Multiply by the gfm of oxygen.
NOOO!!!
YOU’RE A SMART ONE!
Divide 122.6 and finish the problem.
Use a mole to mole
conversion.Run away!
NO COME BACK!
WHOOPS!!
YOU’RE A TRUE CHEMIST!
Convert into a representative
particle.
Finish the problem.
Find the gfm of KCL and place it over moles.
HOW’D YOU GET THAT ANSWER?
RIGHT!
Finish the problem.
Convert into liters.
Convert back into
moles.
UMM…THAT’S NOT CORRECT
GENIUS
50.0g.KCL 15.2g.KCL15g.KCL
OH NOOO!!
REMEMBER SIG FIGS
YEAH YOU DID IT!
