How many of the following oxides are paramagnetic ?
`KO_2,K_2O, K_2O_2`

O_2 is paramagnetic, why?

Which of the following oxides are amphoteric ? Mn_2O_7 , CrO_3 , Cr_2O_3 , V_2O_5

Which of the following oxides are amphoteric? Mn_2O_7,CrO_3,Cr_O_3,V_2O_5

Which of the following can not be oxidized by H_2O_2 ?

Arrange the following in increasing order of basicity- MgO , SrO , K_(2)O , Na_(2)O , Cs_(2)O

Equilibrium constants for the following reactions at 1200 K are given : 2H_2O(g)hArr2H_2(g)+O_2(g):K_1=6.4xx10^(-8) 2CO(g)hArr2CO(g)+O_2(g):K_2=1.6xx10^(-6) The equilibrium constant for the reaction H_2(g)+CO_2(g)hArrCO(g)+H_2O(g) at 1200K will be-

Which of the following is amphoteric oxide ? Mn_(2)O_(7), CrO_(3), Cr_(2)O_(3), CrO, V_(2)O_(5), V_(2)O_(4)

Explain why :Why is KO_2 paramagnetic in nature.

If the equilibrium constants of the following equilibriam SO_2 + 1/2 O_2 rarr SO_3 and 2SO_3 rarr 2SO_2+O_2 are K_1 and K_2 Which shows the correct relation between K_1 and K_2

The relation between K_(p) and K_(c) for the following reaction : 2 SO_(2) (g) + O_(2) (g) hArr 2 SO_(3) (g) is -
