Identifying types of reactions

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, resulting in a new element and a new compound.

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 double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds.

Front

What are the general characteristics of a chemical reaction?

Back

Chemical reactions involve the rearrangement of atoms, the breaking and forming of bonds, and the transformation of reactants into products.

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.

Front

What is an example of a single replacement reaction?

Back

An example of a single replacement reaction is when zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen gas.

Front

What is an example of a decomposition reaction?

Back

An example of a decomposition reaction is the breakdown of water into hydrogen and oxygen gas when an electric current is passed through it.

Front

What is an example of a double replacement reaction?

Back

An example of a double replacement reaction is when sodium sulfate reacts with barium chloride to form barium sulfate and sodium chloride.

Front

How can you identify a single replacement reaction?

Back

A single replacement reaction can be identified by the presence of an element and a compound as reactants, with one element being displaced from the compound.

Front

How can you identify a decomposition reaction?

Back

A decomposition reaction can be identified by a single reactant that breaks down into two or more products.
