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.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

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, adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.

Front

What is the general form of a combustion reaction?

Back

The general form of a combustion reaction is a hydrocarbon reacting with oxygen to produce carbon dioxide and water.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction and are used to balance the equation.

Front

What is the role of subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a molecule and are fixed for a given compound.
