Start! Stoichiometry By: KeyAnna Spratling Date: 5/19/2009
Let’s get started! How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? What do we do first? Set up an equation. Ask Mr. Kirk for help. Give up
Opps! Go Back and Try Again!
No don’t give up! Go Back and Finish What You Started!
Correct! Wow you’re smart How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? Which equation is correct? 2KLCO3→2KCL+3O2 O2+KCLO3→KCL KLCO3→KCL+O2
Opps! OPPS!!! Try Again!
Nice job! How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? 2KLCO3→2KCL+3O2 So, what’s next? Place the given amount over 1. Multiply the given amount by how many elements you have. Divide by the amount of moles.
Sorry Try Again!
Maybe you should pay attention Give it another go!
Awesome! How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? 2KLCO3→2KCL+3O2 25g.KCLO3 1 Then? Convert into liters. Multiply by the gfm of oxygen. Convert into moles, by using the gfm of KCLO3.
Nooo!!! Opps, Try Again!
You’re a smart one! How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? 2KLCO3→2KCL+3O2 25g.KCLO3 1mol.KCLO3 1 122.6g.KCLO3 Next? Divide 122.6 and finish the problem. Use a mole to mole conversion. Run away!
No come back! You Must Finish This Problem!
Whoops!! Let’s Do It Right This Time.
You’re a true chemist! How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? 2KLCO3→2KCL+3O2 25g.KCLO3 1 mol.KCLO3 2 mol.KCL 1 122.6g.KCLO3 2 mol.KCLO3 Now What? Convert into a representative particle. Finish the problem. Find the gfm of KCL and place it over moles.
How’d you get that answer? I Know You Can Do It!
Right! How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? 2KLCO3→2KCL+3O2 25g.KCLO3 1 mol.KCLO3 2 mol.KCL 74.6g.KCL 1 122.6g.KCLO3 2 mol.KCLO3 1mol. Then? Finish the problem. Convert back into moles. Convert into liters.
Umm…that’s not correct You Were So Close!
genius How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? 2KLCO3→2KCL+3O2 25g.KCLO3 1 mol.KCLO3 2 mol.KCL 74.6g.KCL 1 122.6g.KCLO3 2 mol.KCLO3 1mol. What’s the Answer? 50.0g.KCL 15g.KCL 15.2g.KCL
Oh nooo!! You Were So Close!
Remember sig figs Try It Again!
Yeah you did it! How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose? 2KLCO3→2KCL+3O2 25g.KCLO3 1 mol.KCLO3 2 mol.KCL 74.6g.KCL 1 122.6g.KCLO3 2 mol.KCLO3 1mol. 15 grams of KCL Back to Beginning
