Question

Write the chemical reaction of the following:-
1. Reaction used in black and white photography.
2. When glucose is oxidised.
3. Formation of water from hydrogen and oxygen.​

Answer 1

Hey mate,

This is your answer

1.Reaction used in black and white photography is of silver bromide and silver chloride

2.complete oxidation of glucose, respiration principal reaction and the inverse of photosynthesis:

C6H12O6 + 3O2 ——-> 6CO2 + 6H2O

there is partial oxidation to acetaldehyde and formalehyde and down to ethanol or other alcohols.

3.When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. These two processes are represented by the two chemical equations shown at right

Hope this answer help you!!
