Answer:
The temperature at which the reaction changes from non-spontaneous to spontaneous is 588.735 K
Explanation:
The spontaneity of a reaction is determined by the change in Gibbs Free Energy, 
.
If is greater than zero, then a reaction is feasible.
If is less than zero, then a reaction is not feasible.
To determine the temperature at which the reaction changes from non-spontaneous to spontaneous, we should equate the to zero.
We take 
as the limiting condition.
Therefore, the temperature is: 588.735K
1. To make steel
2. It's salts are used to treat anaemia.
3. Pure iron is used in magnets.
4. It is used as a catalyst in the Haber Process which makes ammonia.
5. A very pure iron called wrought iron is used for ornamental gates or fences.
Explanation:
sulphur has a low melting point.
sulphur has a low boiling point thus it can be extracted by pumping hot water which turns it ito solution form
Storms are made from a combination of warm evaporated heat that falls back down near sunset, some fo the jet streams curve for hundreds of miles one of them curves from NA to Antarctica and all the way back in a huge belt, the storm once caught in a jet stream will go where ever the jet stream goes, and a good bit lead across NA.
I hope this helps
