Front

What happens to the mass in a closed system when gas is produced?

Back

In a closed system, the mass stays the same because the gas produced is trapped inside.

Front

What can be predicted about the density of a larger sample of the same liquid?

Back

It would have the same density.

Front

What happens to the mass of the system if gas escapes during a reaction?

Back

It decreases.

Front

What is the significance of using models like Dalton’s for representing particles?

Back

They help visualize particle interaction during chemical reactions.

Front

How can new particles for a substance be formed from old particles?

Back

By rearranging and combining them differently.

Front

What is the law of conservation of mass?

Back

The law states that mass cannot be created or destroyed in a chemical reaction.

Front

What is density?

Back

Density is the mass of an object divided by its volume.

Front

What is a closed system in chemistry?

Back

A closed system is one where no matter enters or leaves, allowing for the study of reactions without mass loss.

Front

What is a chemical reaction?

Back

A process where substances (reactants) are transformed into different substances (products).

Front

What is the role of energy in chemical reactions?

Back

Energy is required to break bonds in reactants and form new bonds in products.
