【原文】 Good evening, everyone. Welcome to today’s show. I’m Jack. In today’s program, I’d like to talk about my favorite novel. It’s Secret Garden by the American writer Burnett. It tells a story about a little girl named Mary who lost her parents and lived with her uncle. In her uncle’s home, there was a secret garden which no one had been in for 10 years. One day a bird led Mary to find the key to the garden and with the help of her friends, they made the garden alive again. Meanwhile, Mary changed from a lonely and cold girl to a lovely and polite girl. Read the book and you’ll find out the magic of nature and the friendship.
How do you like the book Why not pick up one and read with me

四、有机综合推断
(4). 燃烧热指的是1mol纯净物完全燃烧生成稳定氧化物放出的热量,则反应①H2(g)+0.5O2(g)H2O(l) △H=-285.8 kJ·mol-1是表示氢气燃烧热的热化学方程式,所以氢气的燃烧热为△H=-285.8 kJ·mol-1,故答案为-285.8 kJ·mol-1。
22. U形管甲处液面下降,乙处液面上升 B ②③⑤ △H=-265.8 kJ/mol。
【详解】(1)图中若能说明反应是放热反应的,可通过广口瓶中盛有一定量的气体,气体体积受热膨胀,会将U形管中的液体向外压,则U形管现象是:甲处液面下降,乙处液面上升;
(2)A图表示反应物的能量比生成物低,相应反应是吸热反应,与该反应是放热反应不符合;而B图中反应物的能量比生成物的高,发生反应放出热量,反应是放热反应,与该反应的热效应相吻合,故图中能正确表示该反应过程中能量变化的是B;
①将胆矾加热至其变为白色粉末,发生变化吸收热量,与上述能量变化不符合,①不符合题意;
②浓硫酸稀释放出大量热量,与上述能量变化不符合,②符合题意;
③乙醇燃烧放出大量的热量,与上述能量变化相符合,③符合题意;
