Which compound has bond angle nearly 90°?
NH2
SO2
H2O
H2S
Large deposits of sulphur in nature are found in the form of
Flowers sulphur
H2SO4
H2SO3
Free sulphur
Oxygen is prepared commercially from
Sodium and water
Electrolysis of water
KCIO3
HNO3
Which one has the highest bond energy?
O-O
S-S
Se-Se
Te-Te
Ozone reacts with
C2H4
C2H2
C6H6
All
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
Which metal sticks to a glass plate after treatment with ozone
Silver
Mercury
Copper
Lead
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
The geometry of H2S and its dipole moment are
Angular and non-zero
Angular and zero
Linear and zero
Linear and non-zero
