Modeling Conservation of Matter Review

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that the total number of atoms of each element is not changed during a chemical reaction, meaning mass is conserved.

Front

What does mass refer to in science?

Back

Mass refers to how much matter is in an object, typically measured in grams or kilograms.

Front

What occurs during a chemical reaction?

Back

During a chemical reaction, atoms of substances rearrange themselves into a new configuration, forming new substances.

Front

What remains constant during a chemical reaction?

Back

The total number of atoms is conserved, meaning the mass does not change.

Front

What does it mean to conserve something?

Back

To conserve something means to prevent the loss of it, ensuring it remains unchanged.

Front

What is an atom?

Back

An atom is the smallest unit of matter that retains the properties of an element.

Front

What is a chemical reaction?

Back

A chemical reaction is a process where substances (reactants) undergo a transformation to form new substances (products).

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of a substance involved in a chemical reaction.

Front

What is the role of subscripts in chemical formulas?

Back

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

Front

How do you calculate the mass of a substance?

Back

Mass can be calculated using the formula: Mass = Volume x Density.
