Does a physical separation break intermolecular or intramolecular bonds?

Intermolecular bonds

Explanation:

Physical separation is known to break intermolecular bonds. Intermolecular bonds are the bonds between molecules of a substance.

These attractive forces between molecules determines the intermolecular interactions.

Chemical changes takes place between the intramolecular bonds. Intramolecular bonds are found between atoms of a substance. These bonds are the ones that forms new compounds when a product results in a chemical reaction.

Physical separation deals with intermolecular forces of attraction between compounds.

"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
