Question

In the equation below, which of the following is not true?

3 Br2 + 2 Ga 2 GaBr3

Bromine gas is being reduced.

Gallium is the catalyst.

Ga is the reducing agent.

Gallium is gaining electrons.

Answer 1

@paki

Answer 2

what you say...?

Answer 3

so it looks like gallium is gaining electrons but i don't know much about this

Answer 4

yeah u r rite...

Answer 5

oh no it says which is NOT true ugh

Answer 6

here gallium is getting oxidized by losing electrons and hence it is reducing agent...

Answer 7

huh so D isn't right ?

Answer 8

both c and d

Answer 9

so those are eliminated ?

Answer 10

yes

Answer 11

are you thinking Gallium is the catalyst.
?? :)

Answer 12

no

Answer 13

:( oh then you are thinking A ?

Answer 14

no... c and d...

Answer 15

you really confused yourself...

Answer 16

but I thought we said those were eliminated lolol

Answer 17

what...?

Answer 18

nvm ;p
so do you go with d ?

Answer 19

yeah d plus c

Answer 20

hahahahhah but there is only one right answer :-)

Answer 21

not necessary... there may be more than one too...

Answer 22

but i can't summit two answers :''''(

Answer 23

no idea then ,,,

Answer 24

:) it is okay

Answer 25

@study100 :)

Answer 26

@PRAETORIAN.10

Answer 27

i think because bromin is more electronegative therefore it would gain electrons and would an oxidation state of +3
An oxidising agent oxidises something else.
Oxidation is loss of electrons (OIL RIG).
That means that an oxidising agent takes electrons from that other substance.
So an oxidising agent must gain electrons.

reducing agent reduces something else
reduction is gaining of electrons
that means that an reducing agent gives out electrons to another substance to gain.

The oxidation state of an uncombined element is zero.
so both gallium and bromine are 0, as the reaction proceeds and gallium bromide is formed. gallium has an oxidation state of +3 because the sum of the oxidation states of all the atoms or ions in a neutral compound is zero.

Answer 28

omg thank you so much for your explanation!!!

Answer 29

your most welcome :')
