Yes, CaCl2 will dissolve in water.
Oil is not miscible with water.
Methylbenzene, aka toluene, is not miscible in water. It is miscible in organic solvents such as hexane and acetone.
Yes, dichloromethane is miscible in water, meaning it can mix and dissolve in water.
Alcohals are miscible in water and we cannot see anything after stirring it
Water and ethanol. Oil is immiscible with either of those.
Water and ethanol are miscible, forming a homogeneous mixture due to similar polarities. Water and sodium chloride are not miscible as sodium chloride dissociates into ions in water. Water and oxygen are not miscible as oxygen is a gas and does not dissolve in water. Water and gasoline are immiscible due to their differing polarities.
Milk is miscible in other milk products but it is not miscible in water--otherwise you wouldn't see it, or detect it, optically in water.
Yes.
Water and rubbing alcohol are totally miscible.
I
Methanol is miscible in water but Ethyl Acetate is immiscible in water. -- The above answer is correct if asking if each solvent is miscible in water. If you are asking if they are miscible together then the answer is yes, they will mix.
The dissociation equation for CaCl2 in water is: CaCl2 (s) → Ca2+ (aq) + 2Cl- (aq)
