In the following reaction, which element is oxidized and which is reduced?

iron is oxidised and copper is reduced

Explanation:

oxidation means loss of electron so when iron looses 2 electron it becomes more positive so 2+

and cupper recieves 2 electron so +2-2 gives us 0 so copper is normal

the answer is 0.42 is that is an option. this question provides no info

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
