Balancing equations, Single & Double Displacement

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products involved.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction.

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.

Front

What is a subscript in a chemical formula?

Back

A subscript is a number written below and to the right of a chemical symbol that indicates the number of atoms of that element in a molecule.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a chemical reaction where one element replaces another element in a compound.

Front

What is a precipitate?

Back

A precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

How do you predict the products of a double displacement reaction?

Back

To predict the products, swap the cations and anions of the reactants and write the new compounds formed.

Front

What is the importance of balancing chemical equations?

Back

Balancing chemical equations is important because it ensures that the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides of the equation.
