Why does hot water freeze faster than cold water?

Answers

Answer:

Temperature dependency is responsible for the process that hot water freeze faster than cold water.

Explanation:

The effect given above is called Mpemba Effect. According to this idea hot water freezes more quickly as compared to cold water. But until now there is no convincing explanation for this strange phenomenon. One idea is that hot containers make better thermal contact with a refrigerator and so conduct heat more efficiently because a good conductor is good fro the transfer of heat. Another idea about this effect is that warm water evaporates more quickly and since this is an endothermic process, it cools the water making it freeze more quickly.

warm water evaporates rapidly and since this is an endothermic process, it cools the water making it freeze more quickly.

when an iron nail is placed in an aqueous solution of copper(ii)sulphate,a reaction take place.construct an ionic equation for reaction?

Answers

The net ionic equation for this reaction is $Fe(s) \ + \ Cu^(2+)(aq) \ \rightarrow \ Fe^(2+)(aq) \ + \ Cu(s)$ . In ionic equations the soluble compounds are written in their dissociated ion forms. The ionic equation can be determined by knowing the general solubility rules. In this problem there are sulfate compounds involved. It is important to know that sulfates are generally soluble except for sulfates of Ba, Pb, Ag, and Sr. Therefore, the ones dealt with in this problem, CuSO4 and FeSO4, are both soluble in water.

Further Explanation:

The complete equation for this reaction is:

$Fe(s) \ + \ CuSO_(4)(aq) \rightarrow \ FeSO_(4)(aq) \ + \ Cu(s)$

CuSO4 and FeSO4 are soluble in water which will lead to the ionic equation:

$Fe(s) \ + \ Cu^(2+)(aq) \ + \ SO_(4)^ {2-}(aq) \ \rightarrow \ Fe^(2+)(aq) \ + \ SO_(4)^(2-)(aq) \ + \ Cu(s)$

Since the sulfate ion appears on both sides, it is a spectator ion. Spectator ions are unchanged in the chemical reaction and are removed from the net ionic equation:

$\boxed {Fe(s) \ + \ Cu^(2+)(aq) \ \rightarrow \ Fe^(2+)(aq) \ + \ Cu(s)}$

Based on the net ionic equation it can be seen that this is a reduction-oxidation reaction. Iron was oxidized and copper was reduced.
