Theoretical Yield, Percent Yield, Limiting Reactants, & Excess Reactant

Theoretical Yield is the amount of product that...

could form during a reaction.

Theoretical Yield is the maximum amount of product possible from...

a given amount of reactant.

Theoretical Yield is where it means it's the Best Case Scenario. therefore the most amount of...

product that could possibly be made.

Mass to Mass Problems is where moles can't be measured directly, while the mass of...

any substance can generally be easily measured

The 1st Step to Mass to Mass is the mass of the given is...

converted into moles.

The 2nd Step to Mass to Mass is the mass of the given converted into moles of the unknown by...

using the MOLE RSTIO from the balanced chemical equation.

The 3rd Step to Mass to Mass is the moles of the unknown are...

converted to mass.

Mole Ratio is a conversion factor that relates the amounts of moles of any...

two substances in a chemical equation.

Mole Ratios involve the coefficients of the reactants and product in the...

balanced chemical equatio [ NH4NO3 --> N2O + 2H2O ]

An Example of Mole Ratio is...

1 mol NH4NO3 : 1 mol N2O : 2 mol H2O.

The Limiting Reactant [ Limiting Reagent ] is the reactant that gets consumed 1st in a...

chemical reaction and therefore limits how much product can be formed.

In Limiting Reactant [ Limiting Reagent ] the reactants that are left over are called...

excess reactants.

1st Step to Calculating Limiting Reactant is to write the...

balanced chemical equation.

2nd Step to Calculating Limiting Reactant is to convert the mass of the reactants into...

actual moles or reactants available.

3rd Step to Calculating Limiting Reactant is to compare the actual calculated mole ratio to the mole ratio from...

the balanced chemical equation.

4th Step to Calculating Limiting Reactant is to divide the actual mole ratio by the...

coefficients for mole ratios from the equation.

5th Step to Calculating Limiting Reactant is the reactant that produces a LESSER amount of product is...

the limiting reactant, the LARGER amount is the excess reactant.

6st Step to Calculating Limiting Reactant to find the amount of remaining excess reactant, subtract...

the mass of excess reactant consumed from the total mass of excess reactant given.

Calculating mass of product when the given mass of reactants is to multipy the # of the...

limiting reactant by the mole ratio of the product to the limiting reactant, then multipy molar mass.

Theoretical Yield is the maximum amount of product calculated using the...

balanced equation.

Actual Yield is the amount of product obtained when the...

reaction takes place.

Percent Yield is the ratio of actual yield to...

theoretical yield.

The Formula to calculate Percent Yield is...

actual yield (g) / theoretical yield (g) x 100

To calculate the Percent Yield, the actual yield and theoretical yield are...

needed.

1st Step to Calculating Percent Yield is to calculate the...

theoretical yield.

2nd Step to Calculating Percent Yield is to identify the...

actual yield.

3rd Step to Calculating Percent Yield is to divide the actual yield by the...

theoretical yield and multiply by 100.

Step 1 in Finding out Excess Reactant is determine the...

limiting reactant.

Step 2 in Finding out Excess Reactant is use the mass of the limiting reactant to...

determine mass of excess reactant.

Step 3 in Finding out Excess Reactant is subtract the mass of used excess reactant from the...

original amount of excess reactant.

An Excess Reactant is a substance that is not wholly...

consumed or entirely reacted in a chemical reaction
