which of the following would be the limited reagent in the reaction shown below there are 50 molecules of O2 and 50 molecules of H2
You need to do the work for this type problem and learn to do them.
1. Write the balanced equation.
2H2 + O2 ==> 2H2O
2. Convert what you have to mols. Molecules will do so go with what you have.
3. Using the coefficients in the balanced, convert molecules O2 and molecules H2 to molecules H2O. Two separate conversions; i.e., one for H2 and one for O2.
4. The one that produces the fewer molecules of H2O is the limiting reagent.
hahaha i wish i new how to do all that stuff im not very smart but ill try it ill prolly get it wrong anyway but thank you very much
Do what you can and repost what you are confused about. Be sure and explain what it is you don't understand. We can help you through it.
