C10 Flashcards
What is a resource in the context of chemistry?
A resource is a natural substance that can be used for economic gain or practical purposes.
True or False: Renewable resources can be replenished naturally.
True
What is the main difference between renewable and non-renewable resources?
Renewable resources can be replenished naturally, while non-renewable resources are finite and cannot be replaced once depleted.
Fill in the blank: Fossil fuels are considered __________ resources.
non-renewable
What is an example of a renewable resource?
Solar energy
Which process converts biomass into energy?
Biomass conversion
True or False: Water is a non-renewable resource.
False
What is the role of catalysts in chemical reactions?
Catalysts speed up chemical reactions without being consumed in the process.
What is the definition of sustainability in chemistry?
Sustainability refers to the ability to meet current needs without compromising the ability of future generations to meet their own needs.
What is meant by ‘resource efficiency’?
Resource efficiency means using resources in a way that maximizes their value and minimizes waste.
What is one method of reducing resource depletion?
Recycling materials
What does the term ‘extraction’ refer to in the context of resources?
Extraction refers to the process of obtaining raw materials from the earth.
Fill in the blank: The __________ cycle describes the continuous movement of water on, above, and below the surface of the Earth.
water
What is a primary product in chemical resource use?
A primary product is a raw material that is extracted directly from natural resources.
Multiple Choice: Which of the following is a non-renewable resource? A) Wind B) Coal C) Solar
B) Coal
What are the environmental impacts of using non-renewable resources?
Air pollution, greenhouse gas emissions, and habitat destruction.
True or False: All resources can be recycled.
False
What is the main objective of using resources sustainably?
To maintain ecological balance and ensure resources are available for future generations.
What does ‘life cycle assessment’ evaluate?
The environmental impact of a product from raw material extraction through to disposal.
Fill in the blank: __________ energy is derived from the heat of the Earth.
Geothermal
What is the purpose of recycling?
To reduce waste and conserve natural resources.
What is a secondary product in chemical resource use?
A secondary product is produced from processing primary resources.
How does solar energy generation impact the environment?
It reduces reliance on fossil fuels and decreases greenhouse gas emissions.
What is the significance of alternative resources?
Alternative resources provide options for energy and materials that are more sustainable than traditional non-renewable sources.
