Answer:
96g
Explanation:
3.4x10^24 molecules x (1 mol/6.0223x10^23) x (17g/ 1 mol) = 96 g

The heat of a reaction can be calculated from the heat of formation of each substance in the reaction. It is calculated as the sum of the heat of formation of each substance.
<span>C2H2+2H2----> C2H6 ∆H = (-94.5kJ)
2(H2O ----> H2 +1/2O2) ∆H = 2(71.2kJ)
C2H6 + 7/2 O2 -----> 2CO2 + 3H2O ∆H = (-283kJ)
-----------------------------------------------------------------------
C2H2 + 5/2O2 = 2CO2 + H2O </span> ∆H = -235.1 kJ
4CO2 + 2H2O = 2C2H2 + 5O2 ∆H = 470.2 kJ
