Why is NH4+ considered the acid in a reaction
because it donates a proton H+ ions
5 of 17
SiO2 structure
giant covalent network held together by covalent bonds, double bonds
6 of 17
CO2 structure
simple molecular, single bonds
7 of 17
Global Warming Process
-aarth emits Infrared radiation -CO2 absorbs the infrared -CO2 bonds vibrate -more CO2 more infrared absorbed -vibrations cause KE which raises the temperature
8 of 17
Decreasing CO2
plant tress and burn less fossil fuels

When describing catalysts with reference to collisions and activation enthalpy
-catalyst provides a alternative route that has lower activation energy -activation enthaply is the enrgy required for a collision to result in a reaction -more effective and successful collisions occur
