0. A student was given mixture of iron filling and sulphur on heating the mixture. Observe the(a) What was the colour of compound.(b) Write magnetic effect on the mixture.(c) Write the reaction between carbon disulphite and mixture.(d) On adding dilute sulphuric acid or dilute hydrochoric acid what will happen?(e) Name the gas obtained and write two properties.following: |
|
Answer» The color if mixture was beige. it attract toward the mixture because it contains irons.. the gas evovles is hydrogen.. it burns with pop sound Fe(s) + S(s) --> FeS(s) 1. The resulting compound is a dark gray to black.2. Iron will pick up the iron before the reaction, but the magnet will have no effect on the iron(II) sulfide that is produced.3. Carbon disulfide will not affect FeS.4. FeS(s) + 2HCl(aq) --> FeCl2(aq) + H2S(g).... H2S is soluble in water, and produces a slightly acidic solution..... H2S(g) --H2O--> H+ + HS- |
