2,2 Dimethyl oxirane can be cleaved by acid `(H^+)`. Write mechanism.

Which oxide can not be reduced by H_2 ?

Each of HCO_(3)^(-) and HPO_(4)^(2-) can act both as Bronsted acid and base-why? Write the formula of conjugate base and conjugate acid in each case.

Each of HS^(-) and NH_(3) can act as both Bronsted acid and Bronsted base-why? Write the formula of conjugate base and conjugate acid in each case.

(1) HPO_(4)^(2-) can act both as a Bronsted base and as a Bronsted acid. Write the equation of equilibrium established by HPO_(4)^(2-) as an acid and a base in aqueous solution. Also write the expressions of K_(a) & K_(b) in two cases. (2) What are the conjugate acid and base of HS^(-) ?

Can H_2O_2 Solution be concentrated by heating?

Show with proper examples that both HPO_4^(2-) ion and H_2O can act as Bronsted acid as well as Bronsted base.

How can straight chain silicone be produced from dimethyl silicon chloride ? Write with reaction involved .

The decomposition of dimethyl ether leads to the formation of CH_(4) , H_(2) and CO and the reaction -rate is given by Rate k[CH_(3)OCH_(3)]^(3//2) . The rate of reaction is followed by increase in pressure in a closed vessel , so the rate can also be expressed in terms of the partial pressure of dimethyl ether , i.e., Rate =k[P_(CH_(3)OCH_(3))]^(3//2) . If the pressure is measured in bar and time in minutes , then what are the units of rate and rate constants ?
