Iron metal reacts with chlorine gas according to the equation: 2Fe(s) + 3Cl2(g) 2FeCl3(s) If 35.0 g each of iron and chlorine react, how much FeCl3 will be formed?
The highly exothermic thermite reaction, in which aluminum reduces iron (III) oxide to elemental iron, has been used by railroad repair crews to weld rails together. 2Al(s) + Fe2O3(s) 2Fe(s) + Al2O3(s) AH = -850 kJ What mass of iron is formed when 725 kJ of heat are released?
