When phosphours (P_(4)) is heated in limited amount of O_(2).P_(4)O_(6) (tetraphosphorous hexaoxide) is obtained, and in excess of O_(2) , P_(4) O_(10) (tetraphosphours decaoxide) is obtained. i. P + 3 O_(2) rarr P_(4) O_(6) , ii. P_(4) + 5O_(2) rarr P_(4)O_(10) How many moles of O_(2) left unreacted initiallyin reaction (i) ?

When phosphours (P_(4)) is heated in limited amount of O_(2).P_(4)O_(6) (tetraphosphorous hexaoxide) is obtained, and in excess of O_(2) , P_(4) O_(10) (tetraphosphours decaoxide) is obtained. i. P + 3 O_(2) rarr P_(4) O_(6) , ii. P_(4) + 5O_(2) rarr P_(4)O_(10) What mass of P_(4) O_(6) will be produced by the combustion of 2.0 g of P_(4) with 2.0 g of O_(2) .

For the following first order reaction : N_2O_5 (in CCl_4 solvent) to 2NO_2 (solvent) +1/2 O_2(g) the velocity constant is 6.2 times 10^-4 s^-1 . The rate of the reaction at [N_2O_5] =1.25 moles/litre will be:

P_(4)O_(6) and P_(4)O_(10) are formed by burning P_(4) with O_(2) as: P_(4) + 3O_(2) to P_(4)O_(6) P_(4) + 5O_(2) to P_(4)O_(10) What are the masses of P_(4)O_(6) and P_(4)O_(10) that will be produced by the combustion of 2.0 g of P_(4) in 2.0 g of oxygen leaving no P_(4) and O_(2) ?

Asserton :- The formal oxidation no. of sulphur in Na_(2)S_(4)O_(6) is 2.5 Reason :- Two S-atoms are not directly linked with O-atoms.
