Which carbon are u talking about? Carbon in coke is first oxidised to form carbon dioxide - C(s) + O2(g) -> CO2(g). Limestone is decomposed by heat to form calcium oxide and carbon dioxide. CaCO3 -> CaO(s) + CO2(g). The carbon dioxide produced in the two reactions are reduced by carbon in coke to form carbon monoxide. CO2(g) + C(s) -> 2CO(g). The carbon monoxide then reacts with iron (III) oxide in haematite to form iron and carbon dioxide. Fe2O3(s) + 3CO(g) -> 2Fe(l) + 3CO2(g). If ur referring to this last reaction above, 520grams of iron (III) oxide react with 210grams of carbon dioxide. Mol. of Fe203 reacted -> (520/104) = 5mol. Mol of carbon dioxide reacted -> 5 X 3 = 15. Mass of carbon dioxide reacted -> 15 X 14 = 210g
The equation for the reduction of hematite is 2 Fe2O3 + 3 C = 4 Fe + 3 CO2. Every 2 moles of hematite requires 3 moles of carbon. Hematite has a molar mass of 159.69 grams per mole, so there is 3.63 moles. This means there are 5.45 moles of carbon needed.
How many moles of C are needed to react with 0.490 mole SO2?
1.2 Moles
None; everyone knows moles need dirt to live. Wat r u, stupid?
6moles of hydrogen
Ca + 2 H2O ------> Ca(OH)2 + H2 so 2 moles of calcium react with 4 moles of water.
1.35
10 moles of nitrogen dioxide are needed to react with 5,0 moles of water.
How many moles of C are needed to react with 0.490 mole SO2?
1.2 Moles
1.2 Moles
CO2 + H2 -> CO + H2O one to one here 30.6 moles H2O (1 mole H2/1 mole H2O) = 30.6 moles Hydrogen gas needed
None; everyone knows moles need dirt to live. Wat r u, stupid?
The answer is 699 moles perchloric acid.
6moles of hydrogen
Ca + 2 H2O ------> Ca(OH)2 + H2 so 2 moles of calcium react with 4 moles of water.
5C + 2SO2 >> CS2 +4CO 5.44 Mol SO2 (5mol C/2mol SO2 ) = 13.6 Moles of Carbon needed.
These reagents doesn't react.
