Aliya carried out an investigation to study the type of solution formed when a solute is dissolved in a solvent. She found that three spatulas of salt produced a saturated solution when dissolved in 50 ml of water. (a) Draw the particles of the salt water produced when:
(i) one spatula of salt is added into 50 ml of water
(ii) five spatula of salt are added into 50 ml of water

(b) Does heating the water increase the rate of solubility? Give your explanation.​

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer

The kw for water at 0 °c is 0.12× 10–14 m2. calculate the ph of a neutral aqueous solution at 0 °c.

Asample of sea water contains 6.28g of sodium chloride per litre of solution. how many milligrams of sodium chloride would be contained in 15.0ml of this solution?
