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.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, ensure that the number of atoms of each element is the same on both sides of the equation by adjusting coefficients.

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 the significance of the coefficients in a balanced equation?

Back

Coefficients indicate the number of molecules or moles of each substance involved in the reaction.

Front

What is the general form of a combustion reaction?

Back

A combustion reaction typically involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water.

Front

What is the difference between a synthesis reaction and a decomposition reaction?

Back

A synthesis reaction combines two or more substances to form a new compound, while a decomposition reaction breaks down a compound into simpler substances.

Front

What is the role of water in a chemical reaction?

Back

Water can act as a solvent, reactant, or product in chemical reactions, influencing the reaction's conditions and outcomes.

Front

What is an aqueous solution?

Back

An aqueous solution is a solution in which water is the solvent.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.
