Option B, They cannot be separated by using physical properties

I'll go over why the other three options are wrong.

Option A - Boiling water would break the Intermolecular Forces between molecules (Essentially, the force that keeps water molecules stuck together will break, not the force that holds the atoms together)

Option C- Water isn't a mixture (Assuming that it's distilled), and so filtering it would do absolutely nothing.

Option D - There aren't any metallic bonds in water, only polar covalent bonds.

Thus, the only answer left is Option B.

Let me know if you need me to explain anything I mentioned here.

1.consider the following balanced equation and answer parts a through. show calculations for each part.

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.

a solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. the solution is homogeneous and does not settle out. a colloid is intermediate between asolution and a suspension. while asuspension will separate out a colloid will not.
