1.	Which of the following statements is/are correct about slag ?
Answer» The slag is lighter than molten metal The calcium silicate, `CaSiO_3` is obtained is slag formation zone in the extraction of iron from haematite ore In blast furnace/Bessemer converter , the upper layer of molten liquid (i.e. molten metal) is of slag The slag is fusible MATTER. Solution :(A)True statement (B)`CaCO_3 overset(DELTA)toCaO+CO_2` `CaO+SiO_2 to CaSiO_3` These reactions take place in slag formation zone at temperature `~~`1275 K (C ) True statement. (D)INFUSIBLE matter + Flux =Fusible matter (slag)
