Front

What is a subscript in a chemical formula?

Back

A subscript is a number written below and to the right of a chemical symbol that indicates the number of atoms of that element in a molecule.

Front

What is the purpose of balancing chemical equations?

Back

The purpose of balancing chemical equations is to ensure that the number of atoms of each element is the same on both sides of the equation, reflecting the conservation of mass.

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 a chemical 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 a chemical equation.

Front

What is a 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

Why can you only change the coefficient and not the subscript to balance an equation?

Back

Changing the coefficient adjusts the quantity of molecules without altering the identity of the compounds, while changing the subscript would change the compound itself.

Front

What does it mean for a chemical equation to be balanced?

Back

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

Front

How do you determine the missing coefficient in a chemical equation?

Back

To determine the missing coefficient, you can use the method of inspection or algebraic methods to ensure that the number of atoms of each element is equal on both sides.

Front

What is the significance of the arrow in a chemical equation?

Back

The arrow in a chemical equation indicates the direction of the reaction, separating reactants from products.

Front

What is the difference between a chemical equation and a chemical reaction?

Back

A chemical equation is a symbolic representation of a chemical reaction, while a chemical reaction is the actual process that occurs when substances interact.
