Question

MgS + HCl ➝ A + B

KClO₃ ➝ C + D

K₂CO₃ + HCl ➝ D + E + F

NaCl + H₂O ➝ G + H + I

FeS₂ + O₂ ➝ A ➝ B ➝ C ➝ A ➝ D ➝ E

Answer 1

MgS+2HCl\(\rightarrow\) MgCl2 +H2S

2KClO3\(\)t^o\(\rightarrow\) 2Kcl +3o2

K2Co3+ HCl\(\rightarrow\)Kcl +h2o+co2

2Nacl+2h2o\(\rightarrow\) 2Naoh +h2+cl2

Answer 2
