Does hexane and bromine water and sodium hydroxide solution react?

If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.


Sodium oxide soluble?

Sort of. Sodium oxide reacts with water to form sodium hydroxide, which is soluble.


How many moles of water are needed to react with 2.5 moles of sodium?

The balanced chemical equation for the reaction between sodium and water is: 2 Na + 2 H2O -> 2 NaOH + H2 Since 2 moles of water are needed to react with 2 moles of sodium, 1 mole of water is needed to react with 1 mole of sodium. Therefore, 2.5 moles of sodium will require 2.5 moles of water for the reaction.


Is sodium can react with water a chemical change?

The reaction of sodium and water is considered to be a chemical change.


What happens when sodium reacts wid air?

Sodium will normally not react with air. However, it will react with Chlorine. However, that shouldn't be in the air. It will also react with water, but again you need too much water for the air to hold really. That said, going into a steam room with a lump of it would be a bad idea.
