Question

CrBr3 + NaOH + Cl2 ----> NaCrO4 + NaBrO + NaCl + H2O
balance by redox

Answer 1

right hand equation should contain chlorine please see that

Answer 2

recheck the equation

Answer 3

Cr(+3)Br3(-1) + Na(+1)O(-2)H(+1) + Cl2(0) ----> Na(+1)Cr(+7)O4(-2) + Na(+1)Br(+1)O(-2) + Na(+1)Cl(-1) + H2(+1)O(-2)

The oxidation number is enclosed by parenthesis.

Answer 4

is it correct?

Answer 5

yaaa correct

Answer 6

I think I got something wrong. Because when I identified which elements changed an oxidation number I saw more than 2.

Answer 7

elements

Answer 8

let me know them

Answer 9

Cr, Br, Cl

Answer 10

yaaa you are right

Answer 11

equation is right naaa

Answer 12

Is it possible to have 2 reduction and 1 oxidation in an reaction ? or 1 reduction and 2
oxidation

Answer 13

Cr(+3) -Cr(+7)
Cl2(0) -Cl(-)
Br(-) - Br(+1)

Answer 14

yaaa it is possible provided the electrons are balanced properly

Answer 15

after all what is it redox reaction
instead of one reducing agent if you use simaltaneously 2 reducing agent then definately both will reduce and themseleves get oxidised

Answer 16

ok thanks,
BRB

Answer 17

I'll just eat and try to answer this . :)

Answer 18

yaaa good this must be the spirit
