#1
Front (Question)

Elements essential in Fertilisers

Back (Answer)

Nitrogen (N) Phosphorus (P) Potassium (K)

#2
Front (Question)

Natural Fertilisers

Back (Answer)

Decay of dead plants + animals Decay of plant + animal waste

#3
Front (Question)

Synthetic Fertilisers

Back (Answer)

Ammonia (Haber Process) Nitric Acid (Ostwald Process)

#4
Front (Question)

Haber Process

Back (Answer)

Nitrogen + Hydrogen ⇔ Amonia 450ºC 200 atm Iron Catalyst

#5
Front (Question)

Solubility

Back (Answer)

Fertilisers are usually very soluble and can be washed into rivers and lochs, increasing pollution

#6
Front (Question)

Ammonia

Back (Answer)

Invisible gas with a characterstic smell. Very soluble and produces an alkaline solution. Released when ammonium compounds are heated with an alkali

#7
Front (Question)

Ammonia + Acid

Back (Answer)

Forms ammonium salts

#8
Front (Question)

Nitric Acid

Back (Answer)

Formed when brown gas nitrogen dioxide dissolves in water

#9
Front (Question)

Nitrogen Monoxide

Back (Answer)

Formed from nitrogen and oxygen in a lightning storm

#10
Front (Question)

Heavy Elements

Back (Answer)

Formed from lighter elements in stars

#11
Front (Question)

Radioactive Elements

Back (Answer)

Become more stable by giving out alpha, beta or gamma radiation

#12
Front (Question)

Nuclear Equations

Back (Answer)

Written to describe nuclear reactions

#13
Front (Question)

Half-Life

Back (Answer)

Time taken for half of the nuclei of a particular isotope to decay

#14
Front (Question)

Use of Radioactive Isotopes

Back (Answer)

In medicine Cobalt-60 is used to kill cancer cells

#15
Front (Question)

Alpha Particles (α)

Back (Answer)

Made of 2 protons and 2 neutrons (identical to helium nucleus). Heavy and Positively charged

#16
Front (Question)

Beta Particle (β)

Back (Answer)

Made of 1 very fast moving electron. Light and negatively charged

#17
Front (Question)

Gamma Ray (γ)

Back (Answer)

Part of the E-M spectrum. Has no mass, travels at the speed of light and has a very high frequency so a very high energy

#18
Front (Question)

Ionisation

Back (Answer)

When an atom loses or gains an electron giving it a charge

#19
Front (Question)

Alpha Penetration

Back (Answer)

Stopped by a few cm of air or a thin sheet of paper

#20
Front (Question)

Beta Penetration

Back (Answer)

Stopped by a thin sheet of aluminium

#21
Front (Question)

Gamma Penetration

Back (Answer)

Stopped by Lead or Concrete
