Evaporation, condensation, and precipitation are all parts of the water cycle. So the answer would have to be the water cycle.
During the experiment, scientists noted that several of the reaction beakers became hot to the touch. All of the following reactions could cause this result except endothermic and positive ∆H experiments.
<u>Explanation:</u>
If the beakers are becoming hot during experimentation, then that means the energy is being released from the reactants during this experiment. As the energy is being released that enthalpy change will also be negative as the enthalpy change is calculated as the difference of enthalpy of reactants from products.
So in these cases, heat is released making the beakers hot. So for the exceptional case, the experiment should be endothermic in nature and positive enthalpy change should be there in the experiment. Such that the heat will not be released leading to no heating of beakers.
Answer:
The law of heat conduction, also known as Fourier's law, states that the time rate of heat transfer through a material is proportional to the negative gradient in the temperature. As the temperature difference is bigger, the rate of temperature change will be bigger.

sorry if doesnt

9 moles of H2 means you have a total of 18 moles of H2 (9*2). In NH3, the hydrogen comes in sets of 3 (hence H3 at the end) 18/3=6 therefore you need to have made 6 moles of NH3 to satisfy it, since you have enough N2 this can work so you make 6 moles of NH3
A. a higher boiling point and a lower freezing point

hope this helps :)
