Energy transfer during water cycle occurs as follows:
Further Explanation:
Water cycle:
It is the method by which water is being transferred from its gaseous phase to liquid phase and is again converted back to its vapor stats. In order words, water cycle involves movement of water from water vapors to liquid water and then back to water vapors once again.
Steps involved in water cycle:
Step 1: Evaporation
When water is heated, it converts into vapors or evaporation is said to take place. Water from earth’s surface, oceans, rivers and seas is evaporated and form water vapors.
Step 2: Condensation
It is just the opposite of what is observed in evaporation or vaporization. It is procedure that results in conversion of water vapors to liquid water. This process helps in the formation of clouds in the atmosphere.
Step 3: Sublimation
It is direct conversion of solid into gas or vapors. When ice and snow get converted into water vapors without getting converted into liquid water, sublimation is said to take place.
Step 4: Precipitation
It is the process by which water released from cloudsin form of rain, hail, or snow. This process acts as mediator for water delivery from atmosphere to the surface of earth.
Step 5: Transpiration
The process by which water is absorbed by plants and is released in form of water vapors via leaves. It acts as one major source of water in the atmosphere.
Step 6: Runoff
It is the type of precipitation that can neither be evaporated nor be absorbed in the soil. It is important step of water cycle as it is responsible for supply of water to rivers, lakes and seas.
Step 7: Infiltration
This is the process in which infusion of water occurs into the surface of soil and travels deep inside rocks and crevices. Water that is collected from melting ice results in being infiltrated.
Evaporation of water results in conversion of liquid to gas water. Such a conversion requires supply of energy. This energy is released when water vapors get converted into liquid water again. Therefore water gains energy during evaporation and releases it during condensation. Hence option d is correct.

Answer:
0.967mole
Explanation:
Given parameters:
Volume of NH₄Cl = 21.67L
Unknown:
Number of moles = ?
Solution:
We assume that the volume was taken at standard temperature and pressure,
Then;
Number of moles =
Number of moles = = 0.967mole
<u>Answer:</u> The reactant ratio in the given chemical equation will be:
<u>Explanation:</u>
Mole ratio is defined as the ratio of the amount of moles of two substances that are participating in a chemical reaction.
In the given chemical equation:
The reactants are Fe and and the product is
The mole ratio is basically the stoichiometric ratio of the chemical compounds taking part in a chemical reaction.
The mole ratio of reactants is stoichiometric ratio of Fe and , which is:
Hence, the reactant ratio in the given chemical equation will be:
The number of grams : 17.082 g
<h3>Further explanation</h3>Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
453.9 mL of 0.237 M calcium acetate
MW Ca(C₂H₃OO)₂ : 158,17 g/mol
