Balancing Chemical Reactions

Front

What is a balanced chemical reaction?

Back

A balanced chemical reaction has equal numbers of each type of atom on both sides of the equation, following the law of conservation of mass.

Front

How do you determine if a chemical 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.

Front

What is a single-replacement reaction?

Back

A single-replacement reaction is a type of chemical reaction where one element replaces another in a compound, resulting in a new element and a new compound.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat, typically producing carbon dioxide and water.

Front

What is the purpose of balancing chemical equations?

Back

Balancing chemical equations ensures that the same number of atoms of each element are present on both sides of the equation, reflecting the conservation of mass.

Front

What is the coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula in an equation to indicate how many molecules or moles of that substance are involved in the reaction.

Front

How many oxygen atoms are in the compound @@C_4H_8 + 6O_2 ightarrow 4CO_2 + 4H_2O@@?

Back

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 a double-replacement reaction?

Back

A double-replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

How do you balance the reaction @@Ca + CuF_2 ightarrow CaF_2 + Cu@@?

Back

The reaction is already balanced as there is one calcium, one copper, and two fluorine atoms on both sides.
