Answer:
Gas B
Explanation:
diffusion/effusion increases when:
- Temperature increases
- A gas has lower molar mass
- Particles are moving quickly
diffusion/effusion decreases when:
- Temperature decreases
- A gas has higher molar mass
- Particles are moving slowly
Hence: since gas B has the lowest molar mass, it has the highest rate of effusion
I also took the test so I know it is right
D.) Atoms are always in motion
Well uncontrolled cell division can lead to cancer.
Answer:
Hydrogen Peroxide
Explanation:
Hydrogen peroxide is a chemical compound with the formula H₂O₂. In its pure form, it is a very pale blue, clear liquid, slightly more viscous than water. Hydrogen peroxide is the simplest peroxide. It is used as an oxidizer, bleaching agent, and antiseptic. Concentrated hydrogen peroxide, or "high-test peroxide", is a reactive oxygen species and has been used as a propellant in rocketry. Its chemistry is dominated by the nature of its unstable peroxide bond.
