Question
Simple microscope and Compound microscope.
✓
Answer
Simple microscope:
- In a simple microscope, only one convex lens is used.
- In this case, the object is placed within the focal length of the convex lens.
- Its magnifying power is much less than that of a compound microscope.
- It is used to observe minute parts of a watch, to read words in small print, etc.
Compound microscope:
- In a compound microscope, two convex lenses, objective and eyepiece, are used.
- In this case, the object is placed beyond the focal length of the objective lens.
- Its magnifying power is much greater than that of a simple microscope.
- It is used to observe blood corpuscles, plant and animal cells, etc.

Complete the process of iron rusting by filling the blanks. Suggest a way to prohibit the process.
The iron rust is formed due to reaction. Different regions on iron surface become anode and cathode.
Reaction on anode region:

Fe _{( s )} \rightarrow Fe ^{2+}( aq )+2 e ^{-}
$
Reaction on cathode region:
$
O _{2( g )}+4 H ^{+}( aq )+\ldots \ldots . .2 H _2 O _{( l )}
