Reactions in Solution | Stoichiometry (Unit 4)

Front

What is a chemical reaction?

Back

A process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

Front

What is stoichiometry?

Back

The branch of chemistry that deals with the calculation of reactants and products in chemical reactions.

Front

What is a precipitate?

Back

An insoluble solid that forms when two aqueous solutions are mixed and a chemical reaction occurs.

Front

What is a net ionic equation?

Back

An equation that shows only the species that actually participate in a chemical reaction, omitting spectator ions.

Front

What is the mole ratio in a balanced chemical equation?

Back

The ratio of the coefficients of the reactants and products in a balanced chemical equation, indicating the proportions in which they react and are produced.

Front

How do you determine the limiting reactant in a chemical reaction?

Back

By calculating the amount of product each reactant can produce and identifying the reactant that produces the least amount of product.

Front

What is the significance of the temperature change in a chemical reaction?

Back

A temperature change indicates that a chemical reaction has occurred, often due to the release or absorption of energy.

Front

What is the role of aqueous solutions in chemical reactions?

Back

Aqueous solutions provide a medium for reactants to collide and react, often facilitating the formation of products.

Front

What is the difference between a strong electrolyte and a weak electrolyte?

Back

A strong electrolyte completely dissociates into ions in solution, while a weak electrolyte only partially dissociates.

Front

What is the formula for calculating moles from mass?

Back

Moles = mass (g) / molar mass (g/mol).
