FER: Chemical Reactions

Front

What is a chemical reaction?

Back

A process where reactants are transformed into products, involving the breaking and forming of chemical bonds.

Front

What are reactants in a chemical equation?

Back

Substances that undergo a chemical change, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

Substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What does it mean to balance a chemical equation?

Back

To ensure that the number of atoms of each element is the same on both sides of the equation.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it is conserved.

Front

What is a synthesis reaction?

Back

A type of chemical reaction where two or more reactants combine to form a single product (e.g., A + B = AB).

Front

What is a decomposition reaction?

Back

A type of chemical reaction where a single compound breaks down into two or more simpler products (e.g., AB = A + B).

Front

What is a combustion reaction?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.

Front

What is a double replacement reaction?

Back

A type of chemical reaction where two compounds exchange ions or bonds to form two new compounds (e.g., AB + CD = AD + CB).

Front

How do you determine the number of hydrogen atoms in a compound like 4H2O?

Back

Multiply the coefficient (4) by the subscript of hydrogen (2) in H2O, resulting in 8 hydrogen atoms.
