Key terms
Limiting reactant
The reactant that is completely used up in a chemical reaction, determining the maximum amount of product formed.
Excess reactant
The reactant that remains after the limiting reactant is completely consumed in a chemical reaction.
Excess reactant
A reactant that is present in a quantity greater than necessary to completely react with the limiting reactant.
Limiting reactant
The reactant that is completely consumed in a chemical reaction, determining the maximum amount of product formed.
Limiting reactant
The reactant that is completely used up in a reaction, determining the maximum amount of product formed.
Product yield
The amount of product obtained from a chemical reaction, which can be affected by the limiting reactant.
Limiting Reactant
The reactant that is completely used up in a chemical reaction, determining the maximum amount of product formed.
Mole
A unit of measurement for the amount of substance, defined as containing 6.02 x 10^23 particles.
Limiting reactant
The reactant that is completely used up in a reaction, determining the maximum amount of product formed.
Mass in grams
The measurement of the amount of a substance expressed in grams, used to calculate limiting reactants.
Limiting reactant
The reactant that is completely used up in a reaction, determining the maximum amount of product formed.
Balanced equation
A chemical equation in which the number of atoms for each element is the same on both sides, ensuring mass conservation.
Limiting reactant
The reactant that is completely used up in a reaction, determining the maximum amount of product formed.
Percentage yield
The ratio of the actual yield of a product to the theoretical yield, expressed as a percentage.
Concentration
The amount of solute present in a given volume of solution, often expressed in g/dm^3.
Mass per Volume
A way to express concentration, indicating the mass of solute in grams for each cubic decimeter of solution.
Concentration
A measure of the amount of solute present in a given volume of solution, often expressed in grams per cubic decimetre (g/dm^3).
g/dm^3
The unit of concentration representing grams of solute per cubic decimetre of solution. In Concentration of solutions, this term helps explain use grams per cubic decimetre, g/dm^3, as a unit of concentration for AQA GCSE Chemistry 8462 Unit 4.3.
Concentration
The amount of solute present in a given volume of solution, typically measured in grams per cubic decimetre (g/dm³).
Solute
The substance that is dissolved in a solution, resulting in a homogeneous mixture. In Concentration of solutions, this term helps explain calculate the mass of solute in a given volume of solution of known concentration for AQA GCSE Chemistry 8462 Unit 4.3.
Concentration
The amount of solute present in a given volume of solution, often expressed in grams per cubic decimetre (g/dm³).
Solute
The substance that is dissolved in a solution, resulting in a homogeneous mixture. In Concentration of solutions, this term helps explain calculate concentration when given mass of solute and volume of solution for AQA GCSE Chemistry 8462 Unit 4.3.
Concentration
The amount of solute present in a given volume of solution, often measured in grams per cubic decimetre (g/dm^3).
Volume
The amount of space that a substance occupies, typically measured in cubic decimetres (dm^3) or cubic centimetres (cm^3).
Concentration
The amount of solute present in a given volume of solution, often expressed in g/dm^3.
Ratio
A relationship between two quantities, indicating how many times one value contains or is contained within the other.
Concentration
The amount of solute present in a given volume of solution, typically measured in grams per cubic decimetre (g/dm^3).
Rearranging equations
The process of manipulating an equation to isolate a specific variable, such as concentration, mass, or volume.
Concentration
The amount of solute present in a given volume of solution, often expressed in g/dm^3.
Solute
The substance that is dissolved in a solution, resulting in a homogeneous mixture. In Concentration of solutions, this term helps explain (HT only) Explain how mass of solute and volume of solution are related to concentration for AQA GCSE Chemistry 8462 Unit 4.3.
