Answer: As static charge builds up in a storm cloud, the electric field surrounding the cloud becomes ... plasma and the cloud discharges itself to the Earth through a lightning strike. ... These two mechanisms are believed to be the primary causes of the ... The contact point between ground charge and cloud charge rapidly ascends ...
Explanation:The updraft carries the super-cooled cloud droplets and very small ice crystals ... The differences in the movement of the precipitation cause collisions to occur. ... positively charged and the graupel becomes negatively charged (Figure 2). ... but important positive charge buildup near the bottom of the thunderstorm cloud due ...
The answer would be modeling, because craving is when you take a block of something and slice it t make something,and casting is when you put layers over layers to form a something. so the answer will be modeling.
Answer:
None of the above
Explanation:
Henry's law -
This law was given by William Henry in the year 1803 , it is also known as the gas law ,
According to Henry's law , the amount of gas which gets dissolved in a liquid is directly related to the partial pressure of gas that is in equilibrium with the liquid , at a constant temperature .
Or it can stated as ,
The gases' solubility in a liquid is directly related to the partial pressure of gas that is in equilibrium with the liquid .
This law is applicable for sparingly soluble gases in liquid solvents .
And the solubility of a gas is independent of temperature and pressure .
Hence ,
the correct option is None of the above .
The number of moles of O2 that are needed to react with 24 moles of C2H6 is 84 moles of O2
<u><em>Explanation</em></u>
Step 1: write the equation for reaction
= 2C2H6 +7O2 → 4CO2 + 6H2O
Step 2: use the mole ratio to determine the moles of O2
- that is the mole ratio of C2H6 : O2 is 2:7
- therefore the moles of O2= 24 x7/2= 84 moles of O2
