Enthalpy Studies of Hydrogen Bonding

... En2 Title: Enthalpy Studies of Hydrogen Bonding Experiment 1 Objective: To discover the existence of hydrogen bonds between enthanol molecules Result: Initial temperature reading: 26.5? Final temperature reading: 24.5? Questions: 1. The mixing process is endothermic, because since there is a temperature drop, therefore it means heat is absorbed by the solution. There is a temperature change on mixing two liquids, because energy is required to break the bonds. Experiment 2 Objective: To measure the strength of hydrogen bond formed between ethanol Result: Initial temperature change: 25.5? Final temperature change : 23.0? Calculations: Q = -?Cp?m??T = = Question 1. Hexane has to be used in excess, because it is to ensure that all the ethanol is being reacted, so that the result will be accurate. 2. The value is not reliable. Since there may be heat loss to the surrounding, so that the result may not be accurate. Also,we may not take the highest temperature rise from the thermometer, this will

User Reviews of this Essay

What our users think of this essay:

"Poor - extremely brief, missing a number of vital sections. This experimental write-up has only a statement of the 'objective' to begin, and there is no attempt to explain the background theory, give a prediction or even set out the method followed. The results are simple temperature readings, but even the simple statement of the temperature change is omitted. The remainder of the write-up appears to be answering pre-set questions (though the questions themselves are not stated, so the context is rather unclear), and these answers are themselves rather brief, overly limiting the extent of the analysis/evaluation work.
