Answer 1

$2.) \: \: \rm{Al + HCl → AlCl_3 + H_2} \\ \\ \leadsto \boxed{ \pink{\rm{Al + 3HCl →AlCl_3}{ + \: \dfrac{3}{2} H_2}}} \\ \\ \leadsto2 \bigg[ \rm{} Al+ 3HCl →AlCl_3+ \: \dfrac{3}{2} H_2\bigg] \\ \\ \leadsto \boxed{ \pink{\tt{2Al + 6HCl→2AlCl_3 + 3H_2}}}$

$4.) \: \ \rm{ZnS + O_2 → ZnO + SO_2} \\ \\ \leadsto \boxed{ \pink{\rm{ZnS + \frac{3}{2} O_2 → ZnO + SO_2}}} \\ \\ \leadsto { {\rm{2 \bigg[ZnS + \frac{3}{2} O_2 → ZnO + SO_2 \bigg]}}} \\ \\ \leadsto \boxed{ \pink{\tt{2ZnS + 3O_2→ 2ZnO + 2SO_2}}}$

$5.) \: \: \rm{Na + H_2 O → NaOH + H_2} \\ \\ \leadsto \boxed{ \pink{ \tt{2Na + 2H_2 O → 2NaOH + H_2}}}$

$6.) \: \: \rm{C_3 H_8 + O_2 → CO_2 + H_2O} \\ \\ \leadsto \boxed{ \pink{ \tt{C_3 H_8 + 5O_2 → 3CO_2 + 4H_2O}}}$
