What is the completed equation: c3h6+br2->
in chemistry.

Explanation:

First of all, we need to understand that propene, , is an alkene. This can easily be understood from the general formula of alkenes having an expression of . This means when you spot a formula with twice as many hydrogen atoms as carbon atoms, you will have an alkene (or a cycloalkane, but no reaction would take place with a cycloalkane).

Alkenes have a double bond and they produce an addition reaction with bromine water. The evidence for this experimentally is when you mix an alkene with bromine water, the color of the solution disappears.

The two bromine atoms are joined to the two carbons forming a double bond by removing the pi bond and making a saturated molecule with single bonds only. That said, we have a simple addition reaction in which the bromine atoms are added to the molecule.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
