Balancing Chemical Equations Vocab - Exit Ticket

Front

What is a Yield Arrow in a chemical equation?

Back

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

Front

What are Reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the yield arrow.

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 yield arrow.

Front

What is a Coefficient in a chemical equation?

Back

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

Front

What is a Subscript in a chemical formula?

Back

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

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides.

Front

What does it mean to say a chemical equation is balanced?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the yield arrow, indicating the law of conservation of mass is upheld.

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 difference between a chemical equation and a word equation?

Back

A chemical equation uses chemical symbols and formulas to represent a reaction, while a word equation describes the reaction using the names of the substances involved.

Front

What is a skeleton equation?

Back

A skeleton equation is a chemical equation that shows the reactants and products but not the coefficients needed to balance it.
