The geometry of H2S and its dipole moment are
Angular and non-zero
Angular and zero
Linear and zero
Linear and non-zero
Oxalic acid when heated with conc. H2SO4 gives
CO, CO2 and H2O
CO2 and H2S
Oxalic sulphate
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
Which metal sticks to a glass plate after treatment with ozone
Silver
Mercury
Copper
Lead
In Kipp's apparatus, H2S is prepared
Continuously
By FeS + Conc. H2SO4
By FeS + dil. H2SO4
By Fe + dil. H2SO4
Ozone reacts with
C2H4
C2H2
C6H6
All
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
When H2S is passed through HNO3 solution, the product formed is
Milk of S
Colloidal S
Υ-S
β-S
Platinised asbestos used as a catalyst in the manufacture of H2SO4 is an example of
Heterogenous catalysis
Autocatalysis
Homogeneous catalysis
Induced catalysis
When a lead storage battery is discharged
SO2 is evolved
Lead sulphate is consumed
Lead is formed
H2SO4 is consumed
