Question

Write chemical equations involved in the following chemical reactions

(a) White washing

(b) Black and white photography

(c) Burning of natural gas

(d) Respiration

(e) Photosynthesis​

Answer 1

Answer:

a) CaO (s) + H2O Gives CaO

b) AgBr(s) gives Ag(s) + Br(g)

c) CH4 + 2O2 gives CO2 + H2O

d) C6H12O6 + 6O2 gives 6CO2 + 6H2O +ATP

E) 6H2O + 6CO2 +sunlight gives C6H12O6

Answer 2

Hii...Here is solution.

a) White washing is done with a slacked lime.

How it form

→→→→Cao (s) + H2O(L) → caoh2 (aq) calcium hydroxide (slacked lime) used for whitewashi.

Here combination reaction is involved.

-----------------------------

b) Silver chloride is placed in sunlight for white photography.

eq, 2Agcl(s) + sunlight (as a catalyst) → 2Ag (s) + cl2 (g)

Silver bromide is used in black photograph.

eq, Agbr (s) + sunlight (as a catalyst) → Ag (s) + Br (g)

c) CH4 + 2O2 gives CO2 + H2O

d) C6H12O6 + 6O2 gives 6CO2 + 6H2O +ATP

E) 6H2O + 6CO2 +sunlight gives C6H12O6
