Chemical Safety and Green Chemistry

Chemists often work with dangerous chemicals and processes, which can be toxic, explosive, or corrosive. High temperatures and pressures in chemical processes can lead to accidents. Green chemistry aims to reduce these risks by using safer chemicals and minimizing extreme conditions.

Why might chemicals used in a lab be considered dangerous?

• They can be toxic, explosive, or corrosive.

• They are always flammable.

• They are always radioactive.

• They are always acidic.

What are some risks associated with high temperature and pressure in chemical processes?

• They reduce the shelf life of chemicals.

• They can lead to fires and explosions.

• They make chemicals less effective.

• They can cause chemical reactions to stop.

What is a key goal of green chemistry?

• To use more toxic chemicals.

• To increase the use of high temperatures.

• To minimize the potential for accidents.

• To make chemicals more expensive.

How does green chemistry propose to reduce accidents?

• By ignoring safety protocols.

• By using less harmful chemicals.

• By increasing the pressure in processes.

• By using more chemicals.

Which of the following is NOT a principle of green chemistry?

• Using less harmful chemicals.

• Reducing the need for high pressure.

• Minimizing the need for high temperatures.

• Increasing the use of toxic substances.
