问题:

Bissel is a small village of the West Sahara. It lies next to a l.5-square-kilometer oasis(绿洲), from where three days and nights are generally required to go out of the desert. However, before Ken Levin discovered it in 1926, none of the Bissel villagers had ever walked out of the desert. Reportedly, they were not unwilling to leave this barren land. Many had previously tried but failed, always somehow finding themselves back at the oasis after several days of trying to walk out.

When interviewed by Ken Levin, an expert at the British Royal College of Sciences, the villagers explained that no matter which direction they walked it always brought them back to the village.Why couldn’t the Bissel villagers walk out of the desert? Levin was very puzzled. He had, by himself, managed to walk north from the village and reach the nearest town in three and a half days. He decided to carry out an experiment to solve the mystery. He and a Bissel villager called Argutel, would walk out of the desert together. They prepared enough water for a half-a-month journey and two camels. But this time Ken Levin didn't bring his compass. Levin would follow Argutel.

Ten days later, they had walked for about 500 miles but were still in the desert. On the 11th morning, an oasis came into their view. They were back at Bissel. Levin now understood why the Bissel people couldn’t escape the desert. They had no knowledge of the North Star, which had for centuries provided sailors and other travelers with a point of direction. In the desert, if a person goes forward relying only on their senses, they will not be able to travel in a straight line. Rather they will travel in a very large circle and eventually track back to where they began. Levin explained to Argutel the function of the North Star and said, “As long as you rest in the daytime and walk towards the brightest star at night, you would be able to walk out of the desert.” Argutel did as he was told. Three days later, he came to the edge of the desert.

Now in the West Sahara, Bissel has become a bright pearl, where tens of thousands of tourists come every year. Argutel’s bronze statue stands in the center of the town. On its base are the words: __________________________________.

某实验小组对中学课本中可生成氢气的反应进行了研究,总结出三个可以生成H2的反应:①Zn+盐酸②Na+水③Al+NaOH溶液。请回答下列问题:

(1)写出②、③反应的离子方程式②________________;③________________。

(2)在点燃H2之前必须先进行__________________。

(3)实验小组在点燃用上述装置制得的H2时,①③实验获得成功,②却失败了。他们分析认为失败的原因是Na与H2O的反应速率太快,Na的用量太少。于是他们准备增加钠的用量,可老师说太危险,你认为产生危险的原因是_____________。

(4)实验小组查阅钠、苯、水的密度分别为0.97g/mL、0.88g/mL、1.00g/mL,并据此对实验进行了改进。在改进后的实验中H2的生成速率减慢。 原因是________。改进后的实验现象为_________________________________________。
