Francium would react with water by this equation:
2Fr + 2H2O -->2FrOH + H2 The products here are francium hydroxide and hydrogen gas.
However, it would be impossible to gather enough francium to demonstrate this reaction.
No, no weighable amount of Francium has been prepared to test.
Hydrogen Gas
Possibly, though francium is too rare and its half-life too short for it to have any practical uses, there may have been a Francium Bomb tested in the Pacific.
An estimated value may be 0,3 microohm.meter.Yes
Francium has a metallic appearance (http://en.wikipedia.org/wiki/Francium). Due to its extremely short half life, no one has ever seen francium in large enough amounts to be visible. The largest amount of francium ever collected was 10,000 atoms of it. If one were to see a piece of francium however, it would probably appear as a brightly glowing object due to its high rate of decay.</P>
The element with atomic number 119 is a theoretical element and hasn't been observed. However, it does still have an IUPAC systematic placeholder name; which is Ununennium (Uue). Only one attempt has ever been made to make this element. That was in 1985, when Calcium-48 ions were bombarded at Einsteinium-254. It was a failure. If it were to be discovered, it would be the first element of period 8 and would probably fit in under Francium.
Ever since water has existed and been exposed to temperatures below its freezing point. Water has only existed since oxygen was created. That took at least one supernova.

by law they are to be killed at the end of the experiment
Presumably francium -- I don't know whether enough has ever been made to test. Among stable elements, cesium.
It would burn if it were ever possible to collect enough to test. This cannot be done, however, because of Francium's extremely short half-life.

No animal should ever be tested on
If there ever was one on the lake it would be a water spout not a tornado. Tornadoes are on land not water. A water spout is on the water.
Tap water is ever so slightly basic. Hello, I have had two chemistry classes and in each class we tested the pH of tap water and it is slightly acidic, which my prof. said was true. I tested my tap water with pH paper, it was approximately 6.75 which is slightly acidic. Remember that tap water is not natural, it is a product of a water treatment plant.
Nope. They keep the theory the way it is. No one changes it. Usually, when scientist have tested the theory and find out something new, they create a new theory instead of changing the first one.
Water Hockey is real but hardly ever been seen in TV.
Yes there tested at every conteset what ever it's size
No person has ever been to Mars. No spacecraft has ever surveyed Mars and returned to earth. No spacecraft has ever landed on Mars and lifted off again. No liquid water has ever been observed on Mars, and no samples have ever been removed from its surface. In conclusion, we frankly don't know what the question is talking about.
