Balancing Chemical Equations

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound, represented as A + CD -> C + AD.

Front

Define a Chemical Reaction.

Back

A process in which substances undergo chemical changes that result in the formation of new substances.

Front

What is a Combustion Reaction?

Back

A type of chemical reaction that always starts with a hydrocarbon reacting with oxygen, producing carbon dioxide and water.

Front

Balance the equation: H2 + Cl2 -> ?

Back

2HCl.

Front

What is a Double Replacement Reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form two new compounds, represented as AB + CD -> AD + CB.

Front

What is the general formula for a Decomposition Reaction?

Back

AB -> A + B, where a single compound breaks down into two or more simpler products.

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 (A + B -> AB), while a Decomposition Reaction breaks down a compound into simpler substances (AB -> A + B).

Front

What is the Law of Conservation of Mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

What is the purpose of balancing chemical equations?

Back

To ensure that the number of atoms for each element is the same on both sides of the equation, adhering to the Law of Conservation of Mass.

Front

What is a Hydrocarbon?

Back

An organic compound consisting entirely of hydrogen and carbon, commonly used as fuel.
