`S=(h)/(2)[2a+(h-1)d]`, express d in terms of s, h and a.

Using the given diagram, express the following sets in terms of set A and B. (i) {a,d} , (ii) {a,d,c,f}, (iii) {a,d,c,f,g,h}, (iv) {a,d,g,h}, (v) {g,h}

The rate of formation of ammonia by the reaction: N_2+3H_2rarr2NH_3 expressed as (d[NH_3]/(dt))=2.5xx10^(-4)mol L^(-1) s^(-1) The rate of consumption expressed in terms of H_ 2 as (-d[H_2]/(dt)) will be

In the manufacture of NH_(3) by Haber process N_(2)(g) + 3H_(2)(g) to 2NH_(3)(g) the rate of the reaction was measured as - (d[N_(2)])/(dt) = 2 xx 10^(-4) "mol" L^(-1)s^(-1) . The rate of the reaction expressed in terms of H_2 is:

The term phase in S.H.M

(a) Express 72 km/h in m/s. (b) Express 25 m/s in km/h.

Identify the correct statements from the following . (i) Oxygen shows -2,-1,+1 and +2 oxidation states. (ii) The thermal stability of H_(2)O, H_(2)Se and H_(2)S follows the order H_(2)O ltH_(2)S lt H_(2)Se. (iii) The reducing nature of H_(2)Se,H_(2)S and H_(2) Te follows the order H_(2)S ltH_(2)Se ltH_(2)Te
