Metal X forms an oxide that reacts with acids but not with strong alkalis .  Metal y forms an oxide that reacts with acids and strong alkalisMetal Z forms a hydroxide that is not decomposed by heating Which combination BEST identifies X , Y and Z ? AX= calcium , Y = zinc , Z = magnesium BX= iron , Y = aluminium , Z = sodiumCX= aluminium , Y = sodium, Z = calcium DX= magnesium , Y = copper , Z = potassium

Liquid brasses conform to the following relationship: 2 RTInγ^ =-5000xr , Zn Cu where R and T are in cal/deg/mole and K respectively. The vapour pres­ sures of pure copperand pure zinc (in mm Hg) are given as l0= 9 PCu -^τ^- 1.21 log T+ 13.21, and log pZn = - £252. - 0.755 log T + 11.24. Calculate (i) the vapour pressure of copper over a brass containing 40 atom% zinc at 1227°C (1500 K), and ( i i ) the vapour pressure of zinc over the above brass at the same temperature.
