State the nature of CO, Geo. SnO, & PbO. Which allotrope of carbon isured to make super conductor. Why Co can’t be dried using Concentrated `H_2SO_4`.

Why can NH_3 not be dried by using conc. H_2SO_4 ?

State with equation effect of temperature on Boric acid. Why CO can't be dried using concentrated H_2S0_4 . Wht is diborane?

Ethane can be dried by passing through concentrated H_2SO_4 but not ethylene-why ?

Explain why ammmonia cannot be dried by using concetrated H_(2)SO_(4),P_(2)O_(5) or anhydrous CaCl_(2) .

Explain why in the laboratory preparation of H_(2)O_(2) : dilute H_(2)SO_(4) is used instead of concentrated H_(2)SO_(4) ,

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 ?
