How is convection used like on forming tornadoes

atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. different lapse rates within dry and moist air masses lead to instability. mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. special threats from thunderstorms include hail, downbursts, and tornadoes.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
