You just don't ask. You try, you tell us what you did, we push you in the right direction.

so thats my guess...

That could be correct, or maybe not.  Can you write a balanced chemical reaction?  If it's impossible, that may be a hint that the reaction is wrong.  Warning, if it is possible to balance, it may still be wrong.  But at least, you'll have some practice.

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

umm..i appreciate your help. but i really need a accurate answer..even if i can balance it,it doesnt mean that its the correct reaction ..i can write 1000s of balanced equations which are not stable under the lab conditions..:D

can anyone give me a accurate answer?

thanxx

Thiosulfate is obtaining through warming sulfur and sulfite together. Hence decomposition reaction to the starting reagents may be expected.
