Hrxn = -m csystem δt

0.7180 ± 0.0002 g of kno3 was added to 100.00 ± 0.02 g of h2o in a solution calorimeter.

csystem = 121.46 ± 1.23 cal/°c and δt = -0.508 ± 0.009 °c.

(a) (1 pt) calculate the molar enthalpy change δh~rxn for the dissolution of kno3 in water.

(b) (2 pts) calculate in the error in δh~

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
