A. identify which of the following substances dissolve in water, explaining why for each example: ch4, he, mgso4, nahco3 b. which of the following compounds are more likely to dissolve in water and which are more likely to dissolve in gasoline (a nonpolar solvent)? which one dissolves in both and why? c12h22o11, na2so4, kcl, chcl3, ch4, c2h6o

A) MgSO4 and NHCO3 will dissolve in water

B)C12H22O11,Na2SO4 and KCl will dissolve in water

CHCl3,CH4 and C2H6O will dissolve in gasoline

C2H6O will dissolve in both

Explanation:

There is a saying in chemistry that like dissolves like. Polar substances dissolve in polar solvents because they interact effectively with them. Non polar solutes also dissolve in nonpolar solvents.

Ionic substances such as Na2SO4,KCl will dissolve in water.

C12H22O11 contains polar groups which interact with water and lead to its dissolution. C2H6O could interact with water by hydrogen bonding via its OH group and can also dissolve in gasoline because it is an organic substance and volatile. CHCl3,CH4 are purely nonpolar substances which can only dissolve in gasoline.

can you list the answers so i can answer
