LET’S GET STARTED!

Set up an equation.

Ask Mr. Kirk for help.

Give up

Page 3: Stoichiometry

OPPS!

Page 4: Stoichiometry

NO DON’T GIVE UP!

Page 5: Stoichiometry

CORRECT! WOW YOU’RE SMART

2KLCO3→2KCL+3O2 O2+KCLO3→KCL KLCO3→KCL+O2

Page 6: Stoichiometry

OPPS!

Page 7: Stoichiometry

NICE JOB!

Place the given amount over 1.

Multiply the given amount by

how many elements you

have.

Divide by the amount of

moles.

Page 8: Stoichiometry

SORRY

Page 9: Stoichiometry

MAYBE YOU SHOULD PAY ATTENTION

Page 10: Stoichiometry

AWESOME!

Convert into moles, by

using the gfm of KCLO3.

Convert into liters.

Multiply by the gfm of oxygen.

Page 11: Stoichiometry

NOOO!!!

Page 12: Stoichiometry

YOU’RE A SMART ONE!

Divide 122.6 and finish the problem.

Use a mole to mole

conversion.Run away!

Page 13: Stoichiometry

NO COME BACK!

Page 14: Stoichiometry

WHOOPS!!

Page 15: Stoichiometry

YOU’RE A TRUE CHEMIST!

Convert into a representative

particle.

Finish the problem.

Find the gfm of KCL and place it over moles.

Page 16: Stoichiometry

HOW’D YOU GET THAT ANSWER?

Page 17: Stoichiometry

RIGHT!

Finish the problem.

Convert into liters.

Convert back into

moles.

Page 18: Stoichiometry

UMM…THAT’S NOT CORRECT

Page 19: Stoichiometry

GENIUS

50.0g.KCL 15.2g.KCL15g.KCL

Page 20: Stoichiometry

OH NOOO!!

Page 21: Stoichiometry

REMEMBER SIG FIGS

Page 22: Stoichiometry

YEAH YOU DID IT!
