ítѕ ѕímplє.. fσr α chєmícαl єquαtíσn tσ вє вαlαncєd thє numвєr σf chαrgєѕ (єlєctrσn trαnѕfєr) íѕ tσ вє cσnѕídєrєd.
[αl --> αl³+ + 3e- ] ×1
[2H+ + 2e- ---> H2 ] ×3/2
so ..balanced equation is.
Al(s)+3HCl(aq) -->AlCl3 (aq)+3/2 H2
now for 2nd question...
since Al3+ and S2- is the oxidation state of the respective elements , so
Al2S3 product can only be formed.
thus the option a is correct.
