#6
Front (Question)

C4 - The Periodic Table What is the order of reactivity for Group 1?

Back (Answer)

As they go down the group, the reactivity increases (get more reactive)

#12
Front (Question)

C4 - The Periodic Table What is filtration?

Back (Answer)

A layer of sand or gravel filters remaining small particles and sometimes removes microbes

#13
Front (Question)

C4 - The Periodic Table What is sedimentation?

Back (Answer)

Chemicals are added to make solid particles and bacteria settle

#14
Front (Question)

C4 - The Periodic Table What is chlorination?

Back (Answer)

Chlorine is added to kill remaining microbes

#15
Front (Question)

C4 - The Periodic Table What pollutants are found in water?

Back (Answer)

Nitrates - from fertilisers via eutrophication Lead compounds - from water pipes to houses Pesticides - from spraying crops

#16
Front (Question)

C4 - The Periodic Table What is a superconductor?

Back (Answer)

Materials which can conduct electricity with little or no resistance

#17
Front (Question)

C4 - The Periodic Table What are the two types of superconductor?

Back (Answer)

Type I - metals Type 2 - alloys

#18
Front (Question)

C4 - The Periodic Table What are the benefits of superconductors?

Back (Answer)

Loss free power transmission, superfast electronic circuits and powerful electromagnets

#19
Front (Question)

C4 - The Periodic Table What are the difficulties with superconductors?

Back (Answer)

They only work at very low temperatures, limiting their use and superconductors that work at room temperature need to be developed.
