If you had continued following the water molecule in the Water Cycle Activity, what step do you predict would have occurred next
tamaranim1 [39]

Answer:option D is the correct answer, precipitation and it is because water is being released from the cloud into the earth.

Explanation:

PRECIPITATION is the process by which water condenses in the atmosphere. Precipitation can occur in form of snow,fog, dew,rain etc.

Atmospheric water is found in clouds and water vapor. Gradually and systematically the entire atmosphere rotates around the planet. When weather is being formed one of the most common results is precipitation.

In the water molecule activity here, precipitation will occur because water is being released from the atmosphere into the earth.

Licemer1 [7]
The modern day model of an atom has a lot of questions answered about it answered and is very accurate while John's version was a very early model before technology was advanced enough to get more information on it so it was very basic and not as accurate as today's model. Hope this helps!

C2H5OH( l) + 3O2( g) → 2CO2( g) + 3H2O( l); Δ H = –1.37 × 103 kJ Consider the following propositions: I. The reaction is endothe
Svetlanka [38]

Answer:

II. The reaction is exothermic.

III. The enthalpy term would be different if the water formed was gaseous.

Explanation:

For the reaction:

C₂H₅OH(l) + 3O₂(g) → 2CO₂(g) + 3H₂O(l)

The  ΔH is -1.37×10³ kJ. As the change in enthalpy is <0,<em> II. The reaction is exothermic.</em>

The ΔH formation of a compound is different if the chemical is in liquid or gaseous phase. For that reason: <em>III. The enthalpy term would be different if the water formed was gaseous.</em>

<em></em>

I hope it helps!
