Green Chemistry - Principle 5

The video discusses the dangers associated with chemicals and chemical processes, highlighting the risks of toxicity, explosiveness, and the use of high temperatures and pressures. It emphasizes the importance of minimizing these risks through green chemistry, which involves using less harmful chemicals and reducing the need for extreme conditions.

What is a primary concern for workers dealing with chemicals in industrial settings?

• The smell of the chemicals

• The color of the chemicals

• The potential danger they pose

• The cost of the chemicals

Which of the following is NOT a reason why chemicals can be hazardous?

• They can be explosive

• They can be toxic

• They can be colorful

• They can be corrosive

What conditions in chemical processes can lead to serious accidents?

• High temperatures and pressures

• Low temperatures and pressures

• Stable atmospheric conditions

• Neutral pH levels

What is a key principle of green chemistry in preventing accidents?

• Maximizing pressure in processes

• Using less harmful chemicals

• Increasing the amount of heat used

• Using more expensive chemicals

How does green chemistry aim to reduce the risk of chemical accidents?

• By reducing the amount of heat or pressure required

• By ignoring safety protocols

• By increasing the number of chemicals used

• By using more complex processes
