Types of Chemical Reactions flashcard

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: H2 + O2 → H2O.

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. Example: NiCl2 → Ni + Cl2.

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. Example: 3Ca + 2AlCl3 → 3CaCl2 + 2Al.

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. Example: AB + CD → AD + CB.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to the surroundings. Example: Combustion of fuels.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from the surroundings. Example: Photosynthesis.

Front

What happens during a synthesis reaction?

Back

During a synthesis reaction, reactants combine to form a more complex product.

Front

What is the general form of a decomposition reaction?

Back

The general form of a decomposition reaction is: AB → A + B, where AB is a compound that breaks down.

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, resulting in a new element and a new compound.

Front

What is the significance of heat in endothermic reactions?

Back

In endothermic reactions, heat is absorbed, causing a temperature drop in the surroundings.
