Answer 1

1)S+$H_{2}$=$H_{2}$S
2$H_{2}$S+S$O_{2}$=3S+2$H_{2}$O
3S+2Al=$Al_{2} S_{3}$
$Al_{2} S_{3}$+6$H_{2}$O=2Al$(OH)_{3}$+3$H_{2}$S
$H_{2}$S+$O_{2}$=S$O_{2}$+$H_{2}$O
S$O_{2}$+Ca$(OH)_{2}$=Ca$SO_{3}$+$H_{2}$O

2)S+2$CI_{2}$=S$CI_{4}$
S$CI_{4}$+6NaOH=4NaCI+$Na_{2}$$SO_{3}$+3$H_{2} O$
$Na_{2}$$SO_{3}$+$H_{2} O$+S$O_{2}$=NaH$SO_{3}$
NaH$SO_{3}$+NaOH=$Na_{2}$$SO_{3}$+$H_{2} O$
