Dihydrogen sulfide reacts with oxygen gas to form sulfur dioxide and water. How many moles of oxygen gas will react when 0.6469 moles of water are formed?

0.9704 moles of will react when 0.6469 moles of water are formed.

Explanation:

The balanced chemical reaction is:

According to stoichiometry :

2 moles of are formed from = 3 moles of

Thus 0.6469 moles of are formed from =  of

Thus 0.9704 moles of will react when 0.6469 moles of water are formed.

well in order to answer this question you have to provide more information < 3

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
