All
Which compound has bond angle nearly 90°?
NH2
SO2
H2SO4 has very corrosive action on skin because
It reacts with proteins
It acts as dehydrating agent and absorption of water is highly exothermic
It acts as oxidizing agent
It has bleaching action
The reaction in the Kipp's apparatus stops when the outlet is closed from the top because
The acid become weak
Gas pressure breaks the contact between FeS and the acid
Gas starts coming out
Protective film is formed on FeS
Oxygen is prepared commercially from
Sodium and water
Electrolysis of water
KCIO3
HNO3
Platinised asbestos used as a catalyst in the manufacture of H2SO4 is an example of
Heterogenous catalysis
Autocatalysis
Homogeneous catalysis
Induced catalysis
