(4.184 J/g·°C) x (1000 g) x (28.0 - 12.0)°C = 66944 J required
(66944 J) / ((333 J/g) + ((4.184 J/g·°C) x (12.0 - 0)°C)) = 175 g ice
Answer:
It is an example of single displacement reaction.
Explanation:
<u>Single replacement reaction:</u>
A single element replaces another element in a compound.
For example,
The given reaction is as follows.
In the above reaction, aluminium bromide is dissociated into the , these bromide ions are reacted with potassium atoms to form potassium bromide.
Here, only one element displaces therefore, it is an single displacement reaction.
Chemical equivalent of an element is the value obtained by dividing the atomic weight of the given element by its valency. Electrochemical equivalent: Electrochemical equivalent on the other hand, refers to the mass of substance deposited when a current of 1 Ampere is passed for 1 Second during electrolysis. thats the answer when i first saw this i thought it was just one of thos free points with gibberish XD
