一个瓶子,其质量是675克,容积725(?)m~3,盛有2.50克TNT(C_7H_5N_3O_5)和足够同这些TNT完全反应的氧气。瓶内的最初温度是20.0℃,反应的生成物是气态氮气和二氧化碳、液态水。已知1摩尔TNT可放出3.43×10~3KJ的热,玻璃的比热是6.73J/克度。
A bottle with a mass of 675 grams and a volume of 725 (?)m~3 contained 2.50 grams of TNT (C_7H_5N_3O_5) and enough oxygen to react completely with these TNTs. The initial temperature in the bottle was 20.0°C. The products of the reaction were gaseous nitrogen and carbon dioxide and liquid water. It is known that one mole of TNT can release 3.43×10~3 KJ of heat, and the specific heat of the glass is 6.73 J/g.
