Smores Flashcard

Front

What is a balanced chemical equation?

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 during the reaction.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What does it mean if a chemical equation is not balanced?

Back

It means that the number of atoms of each element is not the same on both sides of the equation, violating the law of conservation of mass.

Front

What is the purpose of coefficients in a chemical equation?

Back

Coefficients are numbers placed before compounds in a chemical equation to indicate how many molecules or moles of that substance are involved in the reaction.

Front

What do subscripts in a chemical formula represent?

Back

Subscripts indicate the number of atoms of each element in a molecule.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

How can you tell if a chemical reaction has occurred?

Back

Signs of a chemical reaction include color change, temperature change, gas production, and the formation of a precipitate.

Front

What is an example of a chemical reaction?

Back

An example of a chemical reaction is the combination of sodium (Na) and chlorine (Cl) to form sodium chloride (NaCl), or table salt.

Front

What role do ingredients play in making smores?

Back

Ingredients are the reactants that combine to create the final product, which in this case is the smores.
