Explain how our kidneys filter water and how the universal solvent properties important in that process

Kidneys filter water as Kidneys filter the substance that enters our body using water because water dissolves these substance and send them out of our body. The universal property of water plays a important role in this process as it wash out a great portion even all the substance in our body.

So kidneys filter water and the universal solvent properties plays a important role  in that process.

i think a, hope it .

explanation:

"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"
