Name the four man zones of blast furnace in the extraction of Fe from Fe_(2)O_(3) .

W is the mass of iron (in g) which will be converted into Fe_(3)O_(4) by the action of 18 g of steam on it . What is the value of W/7 ? Fe+H_(2)O to Fe_(3)O_(4)+H_(2)

The temperature of blast furnace to produce iron from its ore Fe_(2)O_(3) varies from 500^(@)C at the top of the furance to about 1900^(@)C at the bottom of the furance. The reaction between the ore Fe_(2) O_(3) and CO at the lowest temperature (~500^(@)C) is

6.0 moles of Fe_(2)O_(3) (s) reacts with 9.0 moles of carbon in a blast furnace according to the equation given below. Fe_(2)O_(3) (s)+ 3C(s)→2Fe(s)+3CO(g) What is the theoretical yield of Fe in moles?

The chief ores of iron are haemalite (Fe_2O_3) , magnetite (Fe_3O_4) , limonite (FeO(OH)) and siderite (FeCO_3) .In the extraction of iron , oxides ores of iron, after concentration through calcination/roasting in reverberatory furnace are mixed with lime stone and coke and fed into a blast furnace. Here, the oxide is reduced to the metal. Which of the following is obtained as a slag in the extraction of iron from haematite ore ?
