Answer:
(a)... 3H2(g) + N2(g) ——> 2NH3(g)
(b)... 2H2S(g) + 3O2(g) ——> 2H2O(l) + 2SO2(g)
(c).... 3BaCl2(aq)+ Al2(SO4)3(aq) ——> 2AlCl3(aq) + 3BaSO4(s)
(d).... 2K(s) + 2H2O(l) ——> 2KOH(aq) + H2( g)
hope it helps you....
Answer:
3h2 + N2 = 2NH3
2H2S + 2O2 = 2H20 + 2So2
3Bacl2 + al2(so4)3 = 2Alcl3 + 3Baso4
2K + 2H20 = 2KOH +H2
