Answer:
Vegetable oil will dissolve in heptane
Isopropyl alcohol will dissolve in water
Potassium Bromide will dissolve in water
Explanation:
In chemistry, like dissolves like. This implies that polar substances will dissolve in polar solvents and nonpolar substances will dissolve in nonpolar solvents. This is so because, dissolution of a solute in a solvent involves adequate intermolecular interaction between solute and solvent which isn't possible between a polar and a nonpolar substance.
The answer is (3) 53.5 g/mol. The gram formula mass means that the mass of one mol compound. 1N=14, 4H=4, 1Cl=35.5. So the gram formula mass of NH4Cl=14+4+35.5=53.5 g/mol.
10.0gNaCl/2.0Lsolution= 5.0g/L
Then we all die because the sun would blow up the earth.
