| A．HCl和NaOH反应的中和热为ΔH=–57.3kJ/mol，则H2SO4和Ca(OH)2反应的中和热为ΔH=2×(–57.3)kJ/mol |
| B．CO(g)燃烧热ΔH=–283.0kJ/mol，则2CO2(g) =" 2CO(g)" + O2(g)反应的ΔH=+2×283.0kJ/mol |
| C．用等体积的0.50mol·L－1盐酸、0.55mol·L－1NaOH溶液进行中和热测定的实验，会使测得的值偏大 |

（10分）植物具有向重力生长的特性，下列是研究根向重力生长机理的两个实验。
实验一：将空白琼脂和含EDTA的琼脂做成帽状，分别套在甲、乙两组玉米胚根的根冠外（示意图如下）。提示：EDTA的作用是去除与其临接部位的 Ca2+。
将胚根水平放置培养一定时间后，观察到甲组胚根向重力（下）生长，乙组胚根水平生长。根据上述实验结果，得出实验结论： 。
实验二：水平放置的胚根弯曲向下生长，与根冠近地侧的Ca2+浓度明显高于远地侧有关。研究表明，根总是朝着Ca 2+浓度高的方向弯曲生长。为验证这一结论，有人设计了下列实验方案。请根据提供的实验材料和用具，写出第二步及以后的实验步骤和实验结果，并回答问题。
（1）实验材料和用具：胚根等长的萌发玉米种子，空白琼脂帽，含EDTA的琼脂帽，上面部分含Ca2+的琼脂帽（水平方向），培养皿等。
（2）实验步骤：
第一步：取若干个培养皿，在每个培养皿中放置适量的萌发玉米种子，按实验一中乙组的方法处理胚根一定时间后，移去根冠外的琼脂帽。然后将培养皿平均分成两组，编号为 A组、B 组。
第二步： 。
第三步： 。
（3）实验结果： 。
（4）科学家进一步证实，根冠中生长素的分布受Ca2+浓度影响，当胚根水平放置时，重力诱导Ca2+向根冠下侧移动，导致近地侧的生长素浓度比远地侧高。请分析胚根的生长素分布与向重力生长的关系： 。 查看习题详情和答案>>
