Finding the limiting reactant can be tricky for several reasons:

1. Complex Math: You often have to do calculations with moles and ratios, which can be tough to understand.

2. Measurement Mistakes: If you measure things wrong, you might get the wrong idea about how much of each reactant you have.

3. Chemical Reactions: Sometimes, reactions don't behave the way you expect. This can make it harder to do the math.

Here’s how you can figure it out more easily:

• Start by finding the balanced chemical equation.
• Next, calculate the number of moles for each reactant.
• Then, use stoichiometry to find out how much of each reactant you need.
• Finally, compare what you have with what you need to find out which reactant is the limiting one.
