Follows an elementary rate law and is carried out isothermally in a flow system. the concentrations of the a and b feed streams are 2 m before mixing. the volumetric flow rate of each stream is 5 dm 3 /min, and the entering temperature is 300 k. the streams are mixed immediately before entering. two reactors are available. one is a gray, 200.0-dm 3 cstr that can be heated to 77 ? c or cooled to

"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"

sure im new too!
