When a lead storage battery is discharged
SO2 is evolved
Lead sulphate is consumed
Lead is formed
H2SO4 is consumed
Oxygen is more electronegative than sulphur yet H2S is acidic while H2O is neutral. This is because.
Water is highly associated compound
H-S bond is weaker than H2O is neutral.
H2S is a gas while H2O is a liquid
The molecular weight of H2S is more than that of H2O
Which one has the highest bond energy?
O-O
S-S
Se-Se
Te-Te
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 geometry of H2S and its dipole moment are
Angular and non-zero
Angular and zero
Linear and zero
Linear and non-zero
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
Ozone reacts with
C2H4
C2H2
C6H6
All
Oxalic acid when heated with conc. H2SO4 gives
CO, CO2 and H2O
CO2 and H2S
Oxalic sulphate
Which metal sticks to a glass plate after treatment with ozone
Silver
Mercury
Copper
Lead
Which of the following isotopes is present in largest amount?
O16
O17
O18
All in equal amounts
