Find the Amount of Excess Reactant (+ Example)
How much of the EXCESS reactant is left over?
* Find the limiting reactant. The OTHER reactants are in excess.
* Use mole ratio to see how much of the excess reactant is used up
* Subtract that from the original amount of excess reactant

This video has changed my life. My whole outlook on everything that exists in this world, in fact even in the entire universe. I can never look at anything I know the same way ever again. This video represents emotions most humans could never comprehend. But I can. Thanks to this video I have been awakened to many things previously thought unimaginable. Thank you.

Your video changed my life. I'm so glad that you make videos like these, I would not be alive otherwise. I hope your channel flourishes and you never need to work another day in your life (from @Orion)
you saved my life, thank you so much
OMG thank you so much watched three vids so far, with at least an hour of work, and this 5 min vid helped more than anything.
Great video!
Very grateful for this clear explanation, thank you
This was really helpful bro Hats off
Please make another video about this 5opic
Thank you so much sir.
Can you share where to find your print out of periodic table please
Does this work for problems other than finding just grams? Such as finding the amount of moles?
Thankkkk youuu mister
Thanks mate
this still makes no sense

Just because this more of something doesn't mean it is in excess. For example lets say you are making a cheese sandwich which needs 2 slices of bread and 1 slice of cheese. If you had something like 8 slices of bread and 5 slices of cheese you would only be able to make 4 sandwiches before running out of bread. Even though we had more slices of bread it was the ingredient that caused us unable to make sandwiches. Now apply the same idea to chemistry. If for example you had 3 grams of hydrogen gas and 16 grams of oxygen gas let's see how much water we can make. The balanced equation for water is 2H2 + O2 --> 2H2O So if you convert that into moles 3g/2.0M = 1.5 mol of hydrogen 16g/32M = 0.5 mol of oxygen Then divide by 1.5 by 2 because there are 2 moles of hydrogen reacting per mole of oxygen. This nets you 0.75 moles Compared 0.75 to 0.5 the oxygen is lower which means it is the limiting reactant. Even though we had much more grams of oxygen than hydrogen it was still the thing that limited the reaction! I hope this comment helped you understand this concept more!
Shoudnot we take hydrigen molarmass 4 because we have 2 moles of 2h

Nope its a mistake lots of students make you need to ignrore any number b4 the reaction
❤
Guys how is h2 is limiting reactant Its 1.5 its higher than 0.95 huh???

After dividing by stoichiometry coefficients,it's 0.75, which is less than 0.90
