对下面符号数字示意图的理解正确的是
“结构决定性质性质决定用途”是学习化学的重要思想方法．下列说法中正确的是 ①钠原子和钠离子质子数相同所以它们的化学性质相同 ②金刚石和石墨中碳原子排列方式不同所以它们的物理性质差异很大 ③水和过氧化氢的分子构成不同所以它们的化学性质不同 ④氮气常温下化学性质稳定所以可用于制氮肥 ⑤洗涤剂具有乳化功能所以可去除油污 ⑥烧碱能与酸发生中和反应所以可用于改良酸性土壤．
如图是某同学测定“小灯泡功率”的实验电路图小灯额定电压为2.5V．在实验中至少要多次调节滑动变阻器电键闭合前滑片P应处于选填“a”或“b”端其目的是使然后接通电路再次调节目的是使．在实验时测得的数据如表．在整理数据计算功率时发现其中一次实验结果与其他两次实验结果相差很大经检查原来是有一个电流的示数读错了．该同学选用的电流表的量程是0﹣0.6安．试分析数据表中第次电流的读数错了正确的应为小灯泡额定功率P额＝瓦．
