Cracking the SAT Chemistry Subject Test

FORMULA REFERENCE GUIDE

•           Density =   

Heat

•           q   =   mcΔT

q   =   Heat

m   =   mass

c   =   specific    heat

                    ΔT  =   Temperature change

Spontaneity

• ΔG = ΔH – TΔS

ΔG  <   0   means   that    a   reaction    is  spontaneous at  this    temperature

•           ΔH  >   0   Endothermic

•           ΔH  <   0   Exothermic

•           ΔT  =   kmi
