Iron powder and sulphur powder were mixed together and divided into two parts A and B. When part A was heated strongly over a burner, then a substance C was formed. The part B was, however, not heated at all. When dilute hydrochloric acid was added to substance C, then gas D was evoled and when dilute hydrochloric acid was added to part B then gas E was evolved.

(a) What type of substance is B ?

(b) What type of substance is C ?

(c) Name the gas (i) D, and (ii) E ?

(d) State one characteristic property of gas D.

(e) Write one test to identify gas E.

Question 35
Iron fillings and sulphur were mixed together and divided into two parts, 'A' and 'B'. Part 'A' was heated strongly while part 'B' was not heated. Dilute hydrochloric acid was added to both the parts and evolution of gas were seen in both the cases. How will you identify the gases evolved?
