The water cycle iss a process which helps to circulate and replenish water on earth.

<h3>What is hydrology?</h3>

Hydrology is the scientific study of water bodies , the changes that occur in them as well as the various features and behavior of water bodies such as oceans and rivers.

Water circulation created by prevailing wind systems. The Gulf Stream is an example up of the Coriolis effect.

The length of open sea over which wind can blow steadily to create waves is called fetch.

Salinity is the amount of dissolved salt in a liquid

The distance from the crest of one wave to the crest of another is called wavelength

Water circulation created by differences in density deepwater currents

Energy is what moves forward and through a wave.

The cyclical process of the changing state and movement of water around the Earth through evaporation, condensation, and precipitation is called water cycle.

As the amount of salt in water increases, the density of the water increases.

The type of energy possessed by moving water is called kinetic energy.

The rising of ocean water bringing nutrients up from the deep us called upwelling.

Therefore, the water cycle helps to circulate and replenish water on earth.

How many moles of sodium hydrogen carbonate are present in 2.61 grams of this compound?
Sloan [31]

Molar mass of NaHCO_3

  • 23+1+12+3(16)
  • 36+48
  • 84g/mol

Now

\\ \sf\longrightarrow No\:of\:moles=\dfrac{Given\:mass}{Molar\:mass}

\\ \sf\longrightarrow No\:of\; moles=\dfrac{2.61}{84}

\\ \sf\longrightarrow No\:of\:moles=0.0312mol

Consider the reaction, C2H4(g) + H2(g) - C2H6(8), where AH = -137 kJ. How many kilojoules are released when 3.5 mol of CH4
antiseptic1488 [7]

Answer: 480 kJ of energy is released when 3.5 mol of C_2H_4 reacts.

Explanation:

The balanced chemical reaction is:

C_2H_4(g)+H_2(g)\rightarrow C_2H_6(g)  \Delta H=-137kJ

Thus it is given that the reaction is exothermic (heat energy is released) as enthalpy change for the reaction is negative.

1 mole of C_2H_4 on reacting gives = 137 kJ of energy

Thus 3.5 moles  of C_2H_4 on reacting gives = \frac{137}{1}\times 3.5=480 kJ of energy

Thus 480 kJ of energy is released when 3.5 mol of C_2H_4 reacts.
