Question

Dr.K asked two brilliant, future PhD students (Dr.A and Dr.B) taking his CHEM I class to determine the structural formula of Hg2Cl6[g]. Both students agree that the structural formula could be determined by reacting Hg2Cl6[g] with AlzCl6[g] to yield HgAICls[g] according to the following reaction: Hg2Cla[g] + AlgClg[g] Rightarrow 2HgAlCls[g] In order to prevent the gas from escaping and to be able to measure the heat released /absorbed. they designed a chamber (system) surrounded by 1 kg of water as depleted below (Fig 1). When the reaction was complete, they observed that the temperature of water surrounding the reaction chamber (system) had decreased from 25.00 degree C to 24.76 Degree C . Based on their observations, the students came up with two different structural formulae for Hg2Cl4 as depleted in the reactions below (Fig 2 and Fig 3). but they could not seem to agree on which structure of Al2cls[g] ans HgAls(g) was more reasonable. (The structures Of Al2Cls[g]) and HgAICIs(g) are well known) Based on your extensive experience to thermochemistry, which struaural formula makes the most sense (supported by data). Explain Reaction chamber. Structure proposed by student Dr. A: Structure proposed by student Dr.B:

Hg2Cl4 makes a ring in it.

it is more stable structure reducing the hindernce
