Lavoisier and the Conservation of Mass

What is the law of conservation of mass?

• Mass increases in a chemical reaction

• Mass decreases in a chemical reaction

• Mass changes form in a chemical reaction

• Mass cannot be created or destroyed in a chemical reaction.

Explain why the law of conservation of mass is important in chemistry.

• It only applies to physics, not chemistry

• It has no relevance in chemistry

• It helps to understand and predict the outcome of chemical reactions.

• It is a myth and not a scientific law

How does the law of conservation of mass relate to the concept of balancing chemical equations?

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

• Balancing chemical equations changes the mass of the elements involved

• Balancing chemical equations has no effect on the number of atoms present

• The law of conservation of mass does not apply to chemical equations

Discuss the difference between mass and weight in the context of the law of conservation of mass.

• Mass is the force exerted on an object due to gravity, while weight is the amount of matter in an object.

• Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

• Mass and weight are the same thing in the context of the law of conservation of mass.

• Mass is the measure of the force of gravity on an object, while weight is the amount of matter in an object.
