Answer #1

Water is polar and dissolves polar copmpounds. ( Like dissolves like)

Among given Nickel(II) sulphate hexahydrate is polar compound and thus will be dissolved in water .

Ther intermolecular interactions beteen Nickel sulphate hexahydrate and water are Hydrogen bonding and dipole -dipole attractions.

Napthalene is non polar compound. Hence it is not souble in water

    Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...

But, as with all crises, there is far more to it than just living beyond one’s means. This story involves rebellion, assassination, fratricide, corruption, money laundering, de-regulation, a lot of investor doubt and a near $50 billion bailout. For the country at least, it has a happy ending. Although...
