AQA GCSE Chemistry 4.10 Using resources overview quiz quiz

A resource being used up faster than it can form

A resource that can be replaced as fast as it is used

A resource that never runs out

A resource made only by chemistry

Using up as many natural resources as possible right now while they are still available

Meeting today's needs without harming future generations' ability to meet theirs

Stopping every single use of natural resources immediately and permanently across the world

Only ever using synthetic, manufactured materials instead of any natural ones at all

Bacteria produce a leachate solution from which the metal is then displaced

The crushed ore is heated strongly with carbon to reduce it to the metal

Plants absorb metal compounds and are then burned to ash

The dissolved metal is simply filtered straight out of ordinary sea water

They are exactly the same thing, since any water that is genuinely safe to drink must also be chemically pure

Pure water is the only kind safe to drink, whereas potable water is always unsafe for people

Potable water contains absolutely no dissolved oxygen at all, but pure water is full of oxygen

Potable water is safe to drink but contains dissolved substances; pure water has only water molecules

Filtering to remove solids and sterilising to kill microbes

Distillation followed by reverse osmosis through a membrane

Adding salt to the water and then boiling it for a long time

Phytomining the water and then bioleaching out the impurities

Filtration

Reverse osmosis

Sterilisation with chlorine

Screening

Measures only the money cost of making and selling a finished product

Tests the chemical purity of the final product once it has been made

Assesses the environmental impact of a product over its whole life

Calculates the relative formula mass of every compound in a product

Advertising the product to potential customers

Setting the final selling price in the shops

Choosing a memorable brand name for the product

Extracting and processing the raw materials

Some impacts are hard to measure and involve value judgements

It always deliberately overestimates the total energy use of a product

It never takes the disposal stage of the product into account at all

It only ever measures the mass of the raw materials and nothing else

It increases the demand for freshly mined ore and the energy that needs

It avoids extracting the metal from its ore, which is energy intensive

It makes the recycled metal noticeably heavier than the original metal

It completely removes the need for any heating during the whole process

Melting down used glass bottles to make brand new ones

Extracting fresh metal from a low-grade ore in the ground

Refilling a glass bottle and using it again

Burning leftover waste material to generate useful energy

They turn finite metal ores into a completely renewable resource that never runs out

They produce no metal at all and are used purely to clean up contaminated land

They are far faster than smelting and replace it completely in modern industry

They extract metals from low-grade ores and avoid the damage of traditional mining
