Heat can be transferred by conduction and convection. which process do you think is quicker? why do you think so?

convection is faster

Explanation:

Convection is faster than the process of conduction. This is because, in the case of convection, which mostly happens in fluids, the molecules have the liberty to move and vibrate from their places at a faster rate, while in conduction, the molecules do not have much space to move and vibrate. Is conduction more efficient than convection.

"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"

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
