What are the Chemical equations to distinguish between alkane and alkene?
Alkenes have a double bond between the carbon atoms (C=C) whereas alkanes have a single bond (C-C). so alkenes are unsaturated compounds, add aqueous solution of Bromine or KMnO4 to both the compounds the decolourization of these reagents confirms the presence of alkenes.
Which elements would you get when electricity is passed through molten lead bromide?
Lead and bromine
Will bromine gas get darker if there is a lot of it?
Bromine gas, like any other transparent colored substance, will appear darker if viewed through a thick layer than through a thin one. Otherwise, the color does not change with amount of material.
What happens when acetylene is bubbled through bromine water?
Acetylene will change colour from orange to colourless.
Why does current pass through salt solution but not through sugar solution?
In order to pass current through a solution you need to have ions in it. Table salt (NaCl) dissolves into Na+ and Cl- ions. Meanwhile sugar does not dissociate into ions in a water solution.
When fluorine gas is bubbled through a solution of sodium bromide the products are free bromine liquid and sodium fluoride in solution is?
The chemical reaction is: 2NaBr + F2 = 2NaF + Br2
What products would you get when you bubble chlorine gas through a sodium bromide solution?
You would get Sodium Chloride and Bromine. This is because Chlorine is a more reactive group 7, (halogen), element that bromine, we know this because it is above bromine in the periodic table group, it is therefore more electronegative. When the reaction occurs, the Chlorine displaces the Bromine and the solution turns brown.
Chlorine Gas is bubbled through a calcium bromide Solution what type of reaction is made?
Chlorine is a more reactive halogen than bromine, therefore, when chlorine gas is bubbled through a calcium bromide solution, the chlorine will take the place of the bromine. This is called an anionic single replacement (displacement) reaction. Cl2(g) + CaBr2(aq) --> Br2(l) + CaCl2(aq)

Why does the color of aqueous potassium bromide change when chlorine gas is bubbled into it?
Chlorine is a stronger oxidizer than elemental Bromine. So, when yellowish chlorine gas is bubbled through the Bromide solution, a red colour is formed which is Bromine. Chlorine oxidizes Bromide ions to elemental Bromine while itself is reduced to Chloride ions. So, the total reaction is: Cl2 + Br- ----> Br2 + Cl-
What passes through a filter a suspension or a solution?
The solution pass through a filter.

How does bromine arrange itself as a molecule?
Bromine doesn't naturally react with itself. it has to made manufacturally in labs to create Br2. As bromine is found in salt just under the earths crust and has to attach itself to other atoms before being able to attach itself to another bromine atom, through a different atom, naturally.
What is unusual aout bromine?
My chemistry is a litte rusty but I believe that Bromine is unusual because it sublimates - goes from solid phase to gaseous phase without going through liquid phase.
What happens when acetylene is bubbled through bromine water?
Acetylene will change colour from orange to colourless.
