Chemical bonding and reactions

Front

What is an ionic charge and how is it represented?

Back

An ionic charge is the electrical charge that an atom or molecule acquires when it gains or loses electrons. It is always written as a superscript.

Front

What does the law of conservation of mass state?

Back

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound, represented as A + CD → C + AD.

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products along with their quantities.

Front

What is the difference between a coefficient and a subscript in a chemical formula?

Back

A coefficient indicates the number of molecules, while a subscript indicates the number of atoms of an element in a molecule.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, adhering to the law of conservation of mass.

Front

What is the significance of the arrow in a chemical equation?

Back

The arrow in a chemical equation indicates the direction of the reaction, separating reactants from products.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds, represented as AB + CD → AD + CB.
