Answer 1

2Fe+2Nacl-------2Fecl2+2Na

k+2H2o-------Koh+2h2

2Al+3Cas------Al2S3+3Ca

2Mg+2H2o -------- Mg(oh)2+H2

4Na+O2------- Na2o

Answer 2

Answer:

a= Fe +2NaCl ____ Fecl2 +2Na

b = 2K + 2H2o --------2KOH + H2

c= 2Al + 3CaS ---------- Al3S4 +3Ca

d= Mg+2h2O --------- mg(OH)2+H2

e= 4Na +O2 -------------2NaO
