Answer 41

Well, it would help you to have a question so someone could help you go over it :p

Answer 42

okay,
02+H2 yields H2O

Answer 43

to calculate percent yield you need to know the theoretical yield and the real yield.
Not all the reactions works 100% efficient, then if a reaction that you theoretically calculate that is going to produce 2kg of a product is only 80% efficient you are not going to get the 2 kg but the 80% of 2Kg that is going to be 1.6kg
in formulas

percent yield = 100 x real yield/ theoretical yield

%yield = 100 x 1.6 kg/2.0 kg = 80%

Answer 44

the limiting reactant is the reactant in the reaction that is in lowest amount to react and the one that is going to determine the theoretical yield of the reaction.
for example if you reaction after balance is
02+2H2 -> 2 H2O
means that you need one mole of O2 to react with 2 moles of H2 to produce 2 moles of H2O
then if you have 3 moles of O2 you will need 6 moles of H2 to produce 6 moles of H2O

Now if you have the 3 moles of O2 but only 3 moles of H2 how many moles of H2O you will be able to produce?
What is going to be the limiting reactant? (the reactant that is in lowest amount)

Answer 45

Whenever you have a reaction, to calculate the limiting reactant first you have to balance the equation and find out the stoichiometry of the reaction. Based in the stoichiometry or the proportion of combinations of the compounds you will be able to calculate how much of one or the other reactants you will need.
Remember the stoichiometry is the relationship in "moles" of the different components in the chemical reaction. If you have the information in grams or liters, you have to convert them to moles to be able to calculate the relationship of combination
