Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Pressure does not affect the reactivity of hazardous waste. Concentration, temperature, and pH all affect the reactivity of hazardous waste.

Multiple choice

Which of the following methods is NOT used to control the reactivity of hazardous waste?

  1. Dilution

  2. Neutralization

  3. Encapsulation

  4. Incineration
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Incineration is not a method used to control the reactivity of hazardous waste. Dilution, neutralization, and encapsulation are all methods used to control the reactivity of hazardous waste.

Multiple choice

What is the most common type of reaction that hazardous waste undergoes?

  1. Oxidation

  2. Reduction

  3. Neutralization

  4. Polymerization
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Oxidation is the most common type of reaction that hazardous waste undergoes. This is because hazardous waste often contains organic compounds, which are easily oxidized.

Multiple choice

What is the most effective method for controlling the reactivity of hazardous waste?

  1. Dilution

  2. Neutralization

  3. Encapsulation

  4. Incineration
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Encapsulation is the most effective method for controlling the reactivity of hazardous waste. This is because encapsulation isolates the hazardous waste from the environment, preventing it from reacting with other materials.

Multiple choice

Which of the following is NOT a hazardous waste?

  1. Asbestos

  2. Lead

  3. Mercury

  4. Salt
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Salt is not a hazardous waste. Asbestos, lead, and mercury are all hazardous wastes.

Multiple choice

Which of the following is a characteristic of hazardous waste?

  1. Ignitability

  2. Corrosivity

  3. Reactivity

  4. Toxicity
Reveal answer Fill a bubble to check yourself
Correct answer
Explanation

Ignitability, corrosivity, reactivity, and toxicity are all characteristics of hazardous waste.

Multiple choice

Which of the following is NOT a method for disposing of hazardous waste?

  1. Landfilling

  2. Incineration

  3. Recycling

  4. Composting
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Composting is not a method for disposing of hazardous waste. Landfilling, incineration, and recycling are all methods for disposing of hazardous waste.

Multiple choice

What is the most important factor to consider when choosing a method for disposing of hazardous waste?

  1. The cost of disposal

  2. The environmental impact of disposal

  3. The safety of disposal

  4. The effectiveness of disposal
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The environmental impact of disposal is the most important factor to consider when choosing a method for disposing of hazardous waste.

  1. Municipal solid waste

  2. Industrial waste

  3. Agricultural waste

  4. Mining waste
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Municipal solid waste is the most common type of hazardous waste generated in the United States. This includes waste from households, businesses, and institutions.

Multiple choice

Which of the following is NOT a source of hazardous waste?

  1. Factories

  2. Hospitals

  3. Schools

  4. Farms
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Schools are not a source of hazardous waste. Factories, hospitals, and farms are all sources of hazardous waste.

Multiple choice

  1. Reduce the use of hazardous materials

  2. Recycle hazardous materials

  3. Dispose of hazardous materials properly

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above are ways to reduce the amount of hazardous waste generated.

Multiple choice

  1. Throw them in the trash.

  2. Recycle them at a local recycling center.

  3. Take them to a hazardous waste disposal facility.

  4. Compost them.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Old light bulbs should be recycled at a local recycling center because they contain hazardous materials.

  1. By reducing the amount of plastic waste that is exported to developing countries.

  2. By improving the management of plastic waste in developing countries.

  3. By promoting the recycling of plastic waste in developing countries.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Rotterdam Convention Amendment on plastic waste will help to reduce plastic pollution by reducing the amount of plastic waste that is exported to developing countries, improving the management of plastic waste in developing countries, and promoting the recycling of plastic waste in developing countries.

Multiple choice

Which of the following is not a type of recycling?

  1. Mechanical recycling

  2. Chemical recycling

  3. Biological recycling

  4. Incineration
