The limiting reactant is the reactant that “limits” a chemical reaction or determines the amount of product that it can produce. It is based on stoichiometry or the mole ratiobetween reactants and products. When you combine reactants, you don’t always use amounts that perfectly balance each other out. For example, if you buy a package of hot dogs a...
There are two main ways of finding the limiting reactant. In both cases, you start with the balanced chemical equation and the number of moles of reactants and products. If you are given the number of moles, great! Usually, you have masses in grams and convert grams to moles. Then, you either compare the mole ratios of the reactants or you see whic...
Here is another example showing how to find limiting reactant: Find the limiting reactant when you react 35.60 grams of sodium hydroxide and 30.80 grams of phosphoric acid to form sodium phosphate and water. First, you need the chemical formulas and balanced chemical equation: 3 NaOH(aq) + H3PO4(aq) → Na3PO4(aq) + 3 H2O(l) The mole ratio between re...

- Nice question! The theoretical yield is maximum 100% by definition. You can run an experiment correctly and still get >100% although It's not quite...
- You are correct. The answer is not 83.9, but 84.6. It's 84.6 instead of 84.7 because of minor rounding issues. Kudos to Texas Instruments.
- If speaking in terms of doing a lab or experiment, the actual yield comes from the actual result of the lab (hence the name).
- You can use whatever units you wish, provided the actual yield and the theoretical yield are expressed in the same units.
- The amount of the reactants would be given to you.
- Theoretical yield is what you think should happen:, and is a calculated amount derived through stoichiometry. Actual yield is what you observed to...

- In general, the theoretical yield is calculated assuming no side reactions will occur (this is almost never actually the case! But still that is th...
- The theoretical yield assumes that all of your reactants (100% of them) react together in the desired reaction to produce your products. But real l...
- The *theoretical molar ratio* is (2 mol Al)/(3 mol Cl₂). Divide numerator and denominator by 3, and the ratio becomes (0.67 mol Al)/(1 mol Cl₂).
Oct 7, 2016 · Many chemical reactions take place until one of the reactants run out. This reactant is known as the limiting reactant. Often it is straightforward to determine which reactant will be the limiting reactant, but sometimes it takes a few extra steps.
There are only 0.25 moles of HCl (instead of 0.3 moles), so the HCl will run out first. It is the limiting reactant.
