Answer:

Explanation:
Hello,
In this case, is possible to infer that the thermal equilibrium is governed by the following relationship:

Thus, both iron's and water's heat capacities are: 0.444 and 4.18 J/g°C respectively, so one solves for the mass of water as shown below:

Best regards.
The answer is 6 moles of water will be produced.
The answer is C. Arrhenius bases increase the concentration of OH- in solution.
