Question

Setarakan persamaan reaksi berikut :

1. N2(g) + H2(g) --- NH3(g)
2. Zn(s) + HCl(aq) --- ZnCl2(aq) + H2(g)
3. FeS(s) + HCl(aq) --- FeCl2(aq) + H2S(g)
4. KOH(aq) + H2CO3(aq) --- K2CO3(aq) + H2O(l)
5. C2H2(g) + O2(g) --- CO2(g) + H2O(g)
6. B + F2 ---BF3
7. P4 + Cl2 --- PCl5
8. Mg + N2 --- Mg2N3
9. PI3 + H2O --- H3PO3 + HI
10. Na + O2 --- Na2O

Answer 1

1. N2 + 3H2 = 2NH3
2. Zn + 2HCl = ZnCl2 + H2
3. FeS + 2HCl = FeCl2 + H2S
5. C2H2 + (5/2)O2 = 2CO2 + H2O
6. B + 3/2(F2) = BF3
7. P4 + 10Cl2 = 4PCl5
8. 2Mg + 3/2(N2) = Mg2N3
9. PI3 + 3H2O = H3PO3 + 3HI
10. 2Na + 1/2(O2) = Na2O
