Answer:
D) Heat flows from the copper cube to the iron cube.
Step-by-step explanation:
The reason comes from the second law of thermodynamics:
Heat energy will flow spontaneously from an area of high temperature to one of low temperature.
When you bring two objects of different temperature into contact, heat energy always moves from the hotter to the cooler object.
The copper cube is hotter than the iron, so heat flows from the copper cube to the iron cube.

I just finished my assignment and this is what I got. Try to put these in your own words. (: Hope this helps.
I think it would be C) The surrounding soil can become very fertile
Answer:
No, it is not enthalpy favored since the chemical system gains energy.
Explanation:
The dissolution of ammonium nitrate in water is an endothermic process.
Endothermic process requires the system to gain energy to can dissolve the particles in water.
So, the reaction is not enthalpy favored.
