Phosphorous Pentachloride + Water – Phosphororic Acid + Hydrogen Chloride C. Zinc + Silver Nitrate – Zinc Nitrate + Silver D. Sodium + Water – Sodium hydroxide + Silver e. Aluminium + Copper Chloride – Aluminium chloride + Copper

Answer 1

A. Ca(OH)2+CO2 gives CaCO3+H2O

B. Zn+2AgNO3 gives Zn(NO3)2+2Ag

E. 2Al+3CuCl2 gives AlCl3+3Cu

D. 2Na+2H2O gives 2NaOH+ H2

Answer 2

A) Ca(OH)2+CO2---CaCO3+H2O(l)

B)PCl5+4H20--H3P04+5HCl(l)

C) Zn(s)+ 2Ag(NO3)(aq)--Zn(NO3)2(aq)+2Ag(s)

D)2Na(s)+2H2O(l)--2NaOH(aq)+H2(g)

E)2Al(s)+3CuCl2(aq)----2AlCl(aq)+3Cu(s)

Hope it helps.
