Answer:
the specific heat of the unknown compound is
Explanation:
Generally the change in temperature of water is evaluated as
Substituting 16.1°C for and 27.4°C for
Generally the change in temperature of unknown compound is evaluated as
Substituting 27.4°C for and 94.3°C for
Since there is an increase in temperature then heat is gained by water and this can be evaluated as
Substituting 179.1 g for m , 4.18 J/g.C for (specific heat of water)
Since there is a decrease in temperature then heat is lost by unknown compound and this can be evaluated as
By conservation of energy law
Heat lost = Heat gained
Substituting 306.9 g for , 8459.6J for
Therefore
