how about the equation.........

What equation?

 

[DANISH182]

What is a " binary compound " ?



Only Alkenes.

but in our textbook it asks for the name of the polymer of butane!!!!

What is a " binary compound " ?



Only Alkenes.

A binary compound is a chemical compound that contains exactly two different elements. Examples of binary ionic compounds include calcium chloride (CaCl2), sodium fluoride (NaF), and magnesium oxide (MgO),

It cant be!
As far as I know, in polymeristaion the double bonds break and form continuous chains............. or something...........so its definately not alkanes!

How do these affect percentage of carbon dioxide in the atmosphere?
1. respiration(3)
2.combustion(3)

It's probably then hydartion reaction, because with the use of butene, water, and an acid catalyst like, H3P04 or sulfuric acid YOU CAN have butane.

But as sj0007 said this can't be an Alkane coz usually polymerization only happens with alkene so...

energy level diagrams ? can anyone explain those ?

don't believe me see it:

don't believe me see it:

What if its a typing mistake?
Maybe they meant butene or it involves chemistry higher than the level of igcse coz as far as I have studied the polymerisation is for alkenes

ok i think so

 

[sj0007]

energy level diagrams ? can anyone explain those ?

In exothermic, since heat is given off, the products have a lower energy
In endothermic, heat is absorbed causing the products to have a higher energy

 

[sj0007]

ok i think so

.............. its possible!

 

[sj0007]

GOOD LUCK EVERYONE!!!

 

[shingiechingz@8]

Is polymerisation only for alkenes or for alkanes also

i think that its for alkenes only

 

[Kiara P.]

GOOD LUCK EVERYONE!!!

Thank youu dear :") !
Same to you !

who is gonna study all night for chemistry p3 and p1?

 

[shingiechingz@8]

a

What equation?

about the oxidation of the ethanol using acidified......

who is gonna study all night for chemistry p3 and p1?

Me.

Me too,best of luck for ur night!!!!!!!!!!!1
