Answer:
solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and soil. As liquid water evaporates or transpires, it forms water vapor and clouds, where water droplets eventually gain enough mass to fall back to Earth as precipitation.
Answer:
K = 0.167
Explanation:
The equilibrium constant, K of a reaction, is defined as the ratio of the concentrations of products and concentrations of reactants.
For the reactions:
A + B ⇄ C + D
For the definition, K is:
K = [C] [D] / [A] [B]
K = [4.0M] [4.0M] / [9.6M] [10.0M]
<h3>K = 0.167</h3>
Answer:
With thermodynamics, one cannot determine <u>the speed of a reaction</u>.
Explanation:
Chemical thermodynamics, a branch of chemistry that deals with study of interrelation of the heat and the work with the chemical reactions or with the physical changes of the state within confines of laws of thermodynamics.
Chemical thermodynamics' structure is derived from first two laws of chemical thermodynamics. From fundamental equations of Gibbs, a multitude of some equations which relates thermodynamic properties of thermodynamic system can be derived and can be used to calculate the reaction spontaneity, equilibrium constant, etc.
<u>Thermodynamics predicts about the direction, feasibility and the extent of a chemical process, it does not tell anything about the rate at which a chemical process may proceed.</u>

66 mph
Explanation:
Average speed is the rate of change of distance with time:
Average speed = 
Given parameters:
Starting point = 88mile marker
End of journey = 121mile marker
time = 30minutes = 0.5hr(60min = 1hr)
Solution:
The distance covered in this journey:
Distance = End of journey - starting point = 121 mile - 88 mile = 33mile
Average speed = 
= 66mph
