Question

photo chemical reaction of AgBr gives _____ gas?​

Answer 1

Answer:

Carbon dioxide gas it will help you

Answer 2

The photochemical reaction of AgBr gives bromine gas.

• Photochemical reactions are those chemical reactions that take place in the presence of light.
• Sunlight initiates a reaction by providing energy to the molecule and this leads the molecules to jump in higher excited states.
• Silver bromide is a light-sensitive compound that is it gets decomposed when exposed to light.
• So when silver bromide is exposed to sunlight, it gets decomposed to give silver metal and bromine gas is liberated.
• The reaction is:

$2AgBr$ → $2Ag+Br_{2}$
