what is the oxidation number of phosphorus in P

Answer 1

\(\Huge\bf\color{#FF0000}W\color{#FF4900}e\color{#FF9200}l\color{#FFDB00}c\color{#FFff00}o\color{#B6ff00}m\color{#6Dff00}e~\color{#00ff00}t\color{#00ff49}o~\color{#00ffDB}O\color{#00ffff}p\color{#00DBff}e\color{#0092ff}n\color{#0049ff}S\color{#0000ff}t\color{#2400ff}u\color{#6D00ff}d\color{#B600ff}y\color{#FF00ff}!\)

That's phosphorus in elemental form, the oxidation number is 0

Answer 2

what is the oxidation number in chlorine in Cl03-

Answer 3

The total of \(\large\sf ClO^{3-}\) is 3-
Oxygen is 2-
3- and 2- combined is 5-
To cancel that out, the Cl has to be 5+

Answer 4

thanks that was right :)

Answer 5

actually it's \(\large\sf ClO3^-\) sorry :P but Cl is still 5+

Answer 6

what is the oxidation number of carbon in H2C2O4 and zinc in Zn(OH)4-2 and chlorine in ClO3-

Answer 7

nevermind the last one i already go that one

Answer 8

Correct explanation for ClO3-
there are 3 O's which are 2-, thats 6- total, with the overal - charge that's 5-,
So the Cl is 5+

Answer 9

Oke for \(\large\sf H_2C_2O_4\)
we know that hydrogen is 1+, and oxygen is 2-
we have 2x hydrogen so that's 2+,
We have 4x oxygen so thats 8-
to cancel the 8- what does the + needs to gain? divide that by 2 because we have 2 carbon atoms

Answer 10

thanks again! :)

Answer 11

so what do you think?

Answer 12

what is the oxidation number of antimony in Sb2O5

Answer 13

wait we were not finished with the last 3...

Answer 14

i already got the other one

Answer 15

what about the zinc in Zn(OH)4-2 and chlorine in ClO3- ?

Answer 16

i got that one too. lol

Answer 17

Oke then \(\large\sf Sb_2O_5\)
O = 2-
we have 5x O so thats 10-
what does antimony needs to be?

Answer 18

i dont know lol

Answer 19

is it +5

Answer 20

the O is 10-
to cancel that out we need Sb to be 10+
we have 2x Sb so what does Sb needs to be?

Answer 21

Yes 5+ is correct :) 10/2=5

Answer 22

sweet! im learning

Answer 23

awesome :P

Answer 24

what is the chlorine in ClO2

Answer 25

O = 2- so 2x O = 4-
you probably know what Cl needs to be now :P

Answer 26

-2

Answer 27

No there is only 1 Cl

Answer 28

wait +3??

Answer 29

and is the oxidation number of lead in Pb =0 ??

Answer 30

Yes it's in elemental state
Cl in ClO2 = 4+

Answer 31

thank you! im terrible at chemistry!

Answer 32

2 Ag+NiO2+H20------->Ag2O+Ni(OH)2 name the element oxidized and name the element reduced

Answer 33

could you post that in a new question? this one is getting long

Answer 34

what do you mean

Answer 35

I mean that's another question.
This question is about oxidation numbers.
