HideShow resource information
exothermic
energy is given out, temperature goes up
1 of 11
endothermic
energy is given in, temperature goes down
2 of 11
hydrated
adding water
3 of 11
unhydrous
without water
4 of 11
chemical reaction
temperature, new things are made, something is being used up
5 of 11
measuring rate
reactions divided by time/ produced dived by time
6 of 11
how temperature speeds up a reaction
collisions must occur
7 of 11
why dos powder react faster than large lumps
smaller particles make larger surface area
8 of 11
