Write the correct balanced equation for solid iron and aqueous copper(ii) bromide react to form solid copper and aqueous iron(ii) bromide

The given reaction is between solid iron and aqueous copper (II) bromide to form solid copper and aqueous iron (II) bromide. Iron being more reactive than copper can displace copper ion from its aqueous solution. Therefore, this reaction is an example of single replacement reaction in which Iron displaces copper from an aqueous solution of copper (II) bromide.

Word equation :

Iron (solid)+Copper(II) bromide(aqueous)--->Copper (solid)+Iron (II) bromide (aqueous)

Chemical equation:

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
