Chemistry question Anyone know how solve it?

The cyanide needs increased to 6 molecules. (It is not “poisonous” enough to balance the equation).

$$\underbrace {\ 10K_4Fe(CN)_6 } _ {Potassium ferrocyanide }\ +\underbrace{122KMnO_4}_{Potassium\ permanganate}\ +\ \ \underbrace{199H_2SO_4}_{Sulphuric\ acid}\\\\ \Rightarrow \ \underbrace{162KHSO_4}_{Potassium\ bisulphate}\ +\ \ \underbrace {5Fe_2(SO_4)_3}_{ferric \ sulphate}\ \ \ +\ \underbrace {122MnSO_4}_{Manganese(II) sulphate}\ +\ \ \underbrace {60HNO_3}_{Nitric\ acid}\ \\\\ \ +\ \underbrace {60CO_2}_{Carbon\ dioxide}\ +\ \ \underbrace {188H_2O}_{water} \\$$

~~D~~

It is a pretty tough one to balance. Here is a helpful website:

Cool presentation, David! I like the labels, too! 

Thank You Aziz. The inspiration comes from studying Heureka’s works of art.

This is a cool work of art. So is the humour.

Ah, trying to slip some cyanide into the forum, are you DavidQD???   Well, you won't get rid of us that easily.........we're too crafty to fall for such a ruse....!!!!

{ BTW.....an impressive dispaly of LaTex !!!! }

Thank you CPhill. How many imperial minims in a minimum daily requirement of CN?

I am impressed too !!!!

Looks like you have quite a fan club David.    

(I found these Chris, you just leave them lying around everywhere.  Finders keepers! )

Ginger your post is very colourful and arty, a little French in origin perhaps?

Your grand total of 2 points looks a little pathetic so I will more than double your points for you.

It is not often that one of my thumbs can have such a dramatic effect.

But, this is the magical land of Camelot, and I am the Lady of the Land.
