The catalyst used in Ostwald's process is platinum gauze containing 55% rhodium.

Which catalyst is used in contact process of manufacturing of H_2SO_4 ?

The catalyst used in the manufactuer ammonia by Haber's process is -

(C_(2)F_(4))_n s a polymeric substance where n is a large number. It is prepared by polymerisation of C_(2)F_4 in presence of sulphur catalyst. The final product is found to contain 0.012% of S. find the value of n if the polymeric molecule contains three S-atoms.

Write the name of the catalyst used in Wacker Process.

Copper sulphate solution (250 mL) was electrolysed using a platinum anode and a copper cathode. A constant current of 2mA was passed for 16 min. It was found that after electrolysis the absorbance of the solution was reduced to 50% of its original value. Calculate the concentration of CuSO_(4) in the solution to begin with.

The hydrocarbon A, adds one mole of hydrogen in the presence of a platinum catalyst to form n-hexane . When A is oxidised vigorouslty with KMnO_4 , a single carboxylic acid, containing three carbon atoms , is isolated. Give the structure of A and explain.

A 10 Watt electric heater is used to heat a container filled with 0.5 kg of water. It is found that the temperature of water and the container rises by 3^@ K in 15 minutes. The container is then emptied, dried and filled with 2 kg of oil. The same heater now raises the temperature of container-oil system by 2^@ K in 20 minutes. Assuming that there is no heat loss in the process and the specific heat of water as 4200 Jkg^(-1) k^(-1) , the specific heat of oil in the same unit is equal to

A 10 Watt electric heater is used to heat a container filled with 0.5 kg of water. It is found that the temperature of water and the container rises by 3, K in 15 minutes. The container is then emptied, dried and filled with 2 kg of oil. The same heater now raises the temperature of container-oil system by 2''K in 20 minutes. Assuming that there is no heat loss in the process and the specific heat of water as "4200 J . kg"^(-1).K^(-1) , the specific heat of oil in the same unit is equal to
