types of reactions

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that is consumed during a chemical reaction, participating in the transformation to form products.

Front

What type of reaction occurs when two compounds exchange ions?

Back

This is known as a Double Replacement reaction.

Front

What is the general form of a synthesis reaction?

Back

A synthesis reaction can be represented as A + B → AB, where two or more reactants combine to form a single product.

Front

What type of reaction is represented by the equation Al(OH)3 → Al2O3 + H2O?

Back

This is a Decomposition reaction, where a single compound breaks down into two or more products.

Front

What is the definition of a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

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 type of reaction is represented by the equation PbCl2 + AgNO3 → Pb(NO3)2 + AgCl?

Back

This is a Double Replacement reaction.

Front

What is the role of products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is an example of a synthesis reaction?

Back

An example of a synthesis reaction is 2H2 + O2 → 2H2O, where hydrogen and oxygen combine to form water.

Front

What is the significance of balancing a chemical equation?

Back

Balancing a chemical equation ensures that the law of conservation of mass is obeyed, meaning the number of atoms of each element is the same on both sides of the equation.
