Question #02fad
1 Answer
The excess reagent is lithium phosphate.
Explanation:
To determine which reactant is in excess, take a look at the balanced chemical equation for this double replacement reaction
Notice that you have a
So, you know that you have 3.4 moles of calcium nitrate and 2.4 moles of lithium phosphate. To see whether or not you'rea dealing with a limiting reagent, check if the mole ratio is respected
This is less than the number of moles available for lithium phosphate, which is 2.4. This means that you have insufficient calcium nitrate.
More specifically, you'd need
in order to react completely with 2.4 moles of lithium phosphate.
Therefore, lithium phosphate is in excess and calcium nitrate is the limiting reagent.
You have an excess of
