Heat of Combustion Questions 1. When bonds are broken‚ energy is required. When bond are formed‚ energy is released. All combustion reactions are exothermic. Suggest a reason for this in terms of the bonds broken and bonds formed. The energy required to break the bonds is greater than the energy required to form. 2. Explain why the heat of combustion of alkanols increases as the length of the carbon chain increases. The heat of combustion of alkanol increases as the length of carbon chain

Do alcohols mixed with a lower non-isomeric parent chain alcohol produce more heat? Table of contents N/A This EEI report addresses the claim that when alcohols are mixed with a lower non-isomeric parent chain alcohol‚ they will produce more heat. This was the basis of the experiment and the hypothesis that inspired it. Background Alcohols are a common substance found in everyday life. From petrol to spirits‚ alcohols are a substantial product used in normal everyday life. Alcohols range from
