[B] The solution becomes blue-green due to formation of copper chloride.
[C] Zi is more than Ze, but nearly equal to Zr
[A] Contraction of the diaphragm muscles
[A] It is acidic in nature Copper oxide (p) is basic in nature since it reacts with an acid to form salt and water.
Glycerine is used for mounting because the peel does not get dried quickly in it.
(i) Agriculture, (ii) Grazing; (iii) Felling of trees; (iv) Hunting and poaching (v) Construction activities are banned in biosphere reserve.
Which of the following could be the possible observation?
[B] The solution becomes blue-green due to formation of copper chloride.
[B] The solution becomes blue-green due to formation of copper chloride.
See lessIn your laboratory you trace the path of light rays through a glass slab for different values of angle of incidence (Zi) and in each case measure the values of the corresponding angle of refraction (Zr) and angle of emergence (Ze). On the basis of your observation your correct conclusion is:
[C] Zi is more than Ze, but nearly equal to Zr
[C] Zi is more than Ze, but nearly equal to Zr

Why do we use glycerine for mounting the peel?
Glycerine is used for mounting because the peel does not get dried quickly in it.
