1) Determine the value of the enthalpy change, AHrxn, for the following reaction using the information below. 2 Fe2O3(s) + 3 C(graphite) — 4 Fe(s) + 3 CO2(g)
C(graphite) + O2(g) + CO2(g)
AH=-393.5 kJ/mol
8 Fe(s) + 6 O2(g) → 4 Fe2O3(s)
AH= -3296.8 kJ/mol

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
