Answer: The aluminium trihalide assists in the heterolytic bond fission of the bromine molecule.
Explanation:
The electrophilic aromatic bromination of acetalinide with molecular bromine requires the formation of Br+. This specie is formed when an Aluminum trihalide reacts with bromine. The Br-Br bond breaks heterolytically such that charged species are produced. This Br+ participates in the electrophilic aromatic substitution and AlX4- is formed where X4 shows a tetrahalide complex of aluminium
Answer:
96.5 grams is the mass of the silver block.
Explanation:
Heat lost by iron will be equal to heat gained by the water
Mass of iron = 
Specific heat capacity of silver= 
Initial temperature of the silver= 
Final temperature = 
Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water =
On substituting all values:
we get, 
96.5 grams is the mass of the silver block.
