5th - Counting Atoms, Classifying and Balancing Equations

Front

What is a balanced equation?

Back

A balanced equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

Front

What is the purpose of coefficients in a chemical equation?

Back

Coefficients are used to balance chemical equations by indicating the number of molecules or moles of each reactant and product.

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that undergo a chemical change in a reaction, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What does the arrow (→) in a chemical equation represent?

Back

The arrow indicates the direction of the reaction, showing that reactants are transformed into products.

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 determine if an equation is balanced?

Back

Count the number of atoms of each element on both sides of the equation; if they are equal, the equation is balanced.
