1. Calculate AH for the reaction: C2H4 (g) + H2 (g) | C2H6 (g), from the following Data. (1) C2H4 (g) + 3 O2 (g) 2 CO2 (g) + 2 H2O (1)
AH, = - 1411. kJ
(2)
C2H6(g) + 342 02 (g) 2 CO2 (g) + 3 H20 (1)
AH, = - 1560. kJ
(3)
H2(g) + 1/2O2(g) | H2O (1)
AH3 = -285.8 kJ
1/4

h let me think

answer; /// i do believe that the correct answer is (a) boiling

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 : )
