GCSE Chemistry (Triple)

that billions of years ago , the earths atmosphere was rich in nitrogen , hydrogen , ammonia and methane and lightening struck , causing a chemical reaction between the gases , resulting in the formation of amino acids . the acids collected in a primordial soup (a body of water out of which life gradually crawled ) the acids combined to produce organic matter which eventually evolved into simple living organisms

amino acids were made , but not as many as there are on earth . This suggets that the theory could be along the right lines but isnt quite right

• carbon dioxide
• methane
• nitrogen
• ammonia
• oxygen

• methanol
• hydrogen cyonide
• diamono methanol

amino acids which are the building blocks of protiens

no as it only shows how some molecules needed for life may have been formed

because we were not there when earth was first formed

• ultimate source
• fractionally distill
• industry

• filtered
• dust
• cooled
• -200
• liquid
• warmed
• helium
• boiling point
• evapourates
• gas
• oxygen
• argon

carbon dioxide and as the world's become more industrialised , more fossil fuels have been burnt in power stations and car engines , this carbon dioxide is thought to be altering our planet

global warming

extra carbon dioxide we are releasing is too acidic . this is bad news for coral and shell fish and it also means that in the future the oceans wont be able to absorb any more carbon dioxide
