Hello there!
In this case, according to the given balanced chemical reaction by which ZnS reacts with O2, it is possible to calculate the moles of the latter that are consumed, not produced, according the 2:3 mole ratio between them and the following stoichiometric set up:
But also, we can compute the moles of SO2 that are produced via the the 2:2 mole ratio of ZnS to SO2:

Answer : The final temperature of the system is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of gold =
Note : Molar heat capacity of gold =
Heat capacity of gold =
= heat capacity of water =
= mass of gold = 13.00 g
= mass of water = 13.00 g
= final temperature of system = ?
= initial temperature of gold =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final temperature of the system is,
