note: . you do q divided by n .the coefficient 2 next to the limiting reactant is important as we multiply the (q/n) by 2 .the + sign next to the answer to show it’s endothermic
what happens in Enthalpy of reaction equation was written for 1 mole
what is the enthalpy change of an element
0 because no reaction is taking place
.enthalpy type given .working out how much one mole releases and multiplying by how many moles given in 1000dm^3 .enthalpy = energy released
if energy is released what sign do you put on the value
negative as it would be exothermic
what would be activation energy of reverse reaction ( original exothermic)
activation energy + enthalpy change
what will the enthalpy of a strong acid and a strong base always be
-57
q/n =
delta h
state and explain one way they could modify the procedure to obtain more accurate results
using a bomb calorimeter to reduce heat loss
what should you never forget with your value
sign
what should you look out for in question
.explain .sf .units .why .state symbols .slight boldness in the letters
when explaining concerns what do you forget
quote part of the definition of delta H that’s being broken by statement
energy is lost ——-
to surroundings
