percentage yield

• equation for percentage yield is :

  actual yield / theoretical yield x 100
• the actual yield is what is obtained/produced from the reaction
• the theoretical yield is what should be made if the reaction is 100% efficient. Its the most/maximum product the reaction can make
• yield -  measure of the quantity of moles of a product formed in relation to the reactant consumed, obtained in a chemical reaction, it's usually expressed as a percentage.
• when one or more reactants run out first, this means that not all the other reactants were able to fully react with them, therefore less than the maximum amount of product was produced
• limiting reagents are the reactant that is entirely used up in a reaction
