Bromine and Iodine are both
totally soluble in mineral oil because these substances are all made up of
non-polar molecules. And because water is a polar molecule, Bromine and Iodine
is not soluble in it.
Non polar solvents contain
bonds that have similar electronegativity, an example of this is carbon and
hydrogen such as gasoline. Some other examples are pentane, hexane, benzene
and toluene.

I believe 1177.8g of CuCl2 can be resolved in 7.8dm3 of H2O if memory serves me correctly. Hope i've been of some assistance to you with this answer. Amaste.
A physical Change, such as a state changing or dissolving, does not create a new substance, but a chemical change does.In a chemical reaction the atoms and molecules that interact with each other are called reactants.In a chemical change reaction the atoms and molecules produced by the reaction are called products.only the atoms present in the reactants can end up in the products. No new atoms are created and no atoms are destroyed. Reactants contact each other, bonds between atoms in the reactants are broken,and atoms rearrange and form new bonds to make new products.
Answer:
true
Explanation:
Hotter things have more heat energy than colder things. That's because the atoms or molecules move around faster in hot things (red, right) than they do in cold things (blue, left). ... The more heat you supply, the faster the molecules move and the further apart they get.
Answer: These results show that the body regulates its salt and water balance not only by releasing excess sodium in urine, but by actively retaining or releasing water in urine.
