Balancing and Classifying Chemical Equations

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products along with their respective quantities.

Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means ensuring that the number of atoms of each element is the same on both sides of the equation, adhering to the law of conservation of mass.

Front

What are the coefficients in a chemical equation?

Back

Coefficients are the numbers placed before the compounds in a chemical equation to indicate the number of molecules or moles of each substance involved in the 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 the anions and cations of two different compounds exchange places, forming two new compounds.

Front

How do you identify the type of reaction?

Back

To identify the type of reaction, analyze the reactants and products to see if they fit the definitions of synthesis, decomposition, single replacement, or double replacement.

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 the significance of balancing chemical equations?

Back

Balancing chemical equations is crucial because it reflects the actual quantities of reactants and products involved in a reaction, ensuring accurate stoichiometric calculations.
