∆H is the exchange in enthalpy from reactants to products A ΔHº charge represents an addition of electricity from the reaction and from the surroundings, resulting in an endothermic response. A horrible cost for ΔHº represents the removal of power from the reaction and into the surroundings and so the reaction is exothermic.

The enthalpy of a system can not be measured right away because of the fact the inner energy consists of additives that are unknown, now not effects available, or aren't of interest in thermodynamics.

Hence, the answer is option A.

umka21 [38]

Answer:

ethane=c2h6

ethyne=c2h2

ethene=c2h6

Explanation:

ethane has single bond between carbon atoms(it is alkane.) ethyne has triple bond between carbon atoms(it is alkyne) ethene has double bond between carbon atoms (it is alkene)
