The empirical formula of an organic compound can be determined via combustion analysis. A typical combustion apparatus is shown below: omi alateyro to moras llam asosiy infor IN-SONDT STUIDTons or broen breno si mate8906 Quat-lom adtatni adut od 90015 gai edw.10d, tiste or vbleu d has yetom sigume or doin H₂O is trapped here, missed 10 91m sill 15wol, CO₂ is trapped here UC ob nas uov ini em or wood lab excess O₂ is added 0000 xuntas ng 199 of nun tent Hoy non so nun ba fuberg 10000.00 000 00 000000000000000000 00000000000000000 butiomaa grilom ai ost of domaile TOXDU 00E of solo al Y bruoqmnes to taloq gais sample is heated until it decomposes er lirw 21sismoodi solo odi 400) 19T of 17 A sample of the chemical is burned in oxygen in a tube packed with copper oxide to ensure complete combustion. The carbon in the compound is converted to CO2, which is absorbed in a tube packed with ascarite. The hydrogen is converted to water vapor and is absorbed in a tube packed with drierite. The increase in weight of the absorber tubes corresponds to the CO₂ and H₂O produced during combustion. Compounds X and Y do NOT contain any nitrogen, sulfur, or halogen atoms; both compounds do contain oxygen. bioA oiosasdonimA-A A 1.0542 g sample of X was burned in a combustion apparatus.

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
