Compare the forces of attraction between molecules in water, sugar and oxygen. Rank them in order from greatest to least. A) water, sugar, oxygen B) oxygen, water, sugar C) sugar, water, oxygen D) sugar, oxygen, water

Option C, sugar, water, oxygen

Explanation:

Force of attraction leads to closer placing of atomic particles in any element or molecule. The higher the force of attraction, the more compact is the arrangement of the atomic particle.

Thus, in a solid the atomic particles are closely packed followed by a liquid and then a gas.

As we know sugar is solid, water is liquid and oxygen is gas.

Thus, forces of attraction between molecules of sugar will be the highest followed by water and then oxygen

Hence, option C is correct

"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"
