Bath Bomb #2 Flashcard

Front

What happens to the flame when gas is produced and trapped in a closed system during a flame test?

Back

The flame is extinguished.

Front

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

Back

By rearranging and combining them differently.

Front

What occurs when electricity is run through water?

Back

Gas bubbles appear and rise to the surface.

Front

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

Back

The mass stays the same because the gas produced is trapped inside the closed system.

Front

What is the composition of water in terms of hydrogen and oxygen atoms?

Back

Water is composed of 2 hydrogen atoms and 1 oxygen atom.

Front

What evidence supports the idea that water is made of hydrogen and oxygen?

Back

Gas bubbles produced in the test contained hydrogen gas produced at twice the rate and volume as oxygen gas.

Front

What is a closed system in the context of gas production?

Back

A closed system is one where no matter can enter or leave, so all produced gas remains contained.

Front

What is the significance of gas bubbles in a chemical reaction involving water?

Back

Gas bubbles indicate that a chemical reaction is occurring, often involving the production of gases.

Front

How does the law of conservation of mass apply to chemical reactions?

Back

The law states that mass is neither created nor destroyed in a chemical reaction; it remains constant.

Front

What is the role of electricity in the electrolysis of water?

Back

Electricity is used to break down water into hydrogen and oxygen gases.
