-4. (a) 48 + 502 . 2 P. Os ... - 5 moles of Oz gives & moles P2O5 .. a 3.4 moles of Oz would give 2 X3.4 = 1.36 modes Pos (6) 4 moles of P are required to react with 5 - moles of O2 & 30.1 mole of Op would require 4 x 20.1 = 24.08 mole off 5. (a) Alls + Culla (aq) + AlCl3 (aq) + Cu(A) . As there are even no. of d on reactant side : and odd no. of (i on product side to make the no. of 4 equal multiplying Culla by 3 and Ach by 2 Alla) + 3 culla (aq) + 2A1CI₂ (aq) + (411) - finally balancing Al and Cu by multiplying Alby 2 Cu by 3 ZAIC) + 3 Cullocar * LAICI (aq) + 3(414) (6) 3 moles of Culle gives 2 males AlCl3 8 6 moles of Cullo would give 2x2 = 4 mole AlCl₃ (C) a moles of AlCl3 were formed from 3 mole Culle .. 4.5 mole of Ally would require Z x 4.5= 6.75 mole of Culla
