In the process of isolating iron from its ores, carbon monoxide reacts with iron (III) oxide, as described by the equation:
Fe2O3(s) + 3CO(g) --> 2Fe(s) + 3CO2(g) ?H = -24.8 kJ
The enthalpy change for the combustion of carbon monoxide is:
2CO(g) + O2(g) --> 2CO2(g) ?H = -566 kJ
Use the preceding thermochemical equations to calculate the enthalpy change (in kJ) for the equation:
4Fe(s) + 3O2(g) --> 2Fe2O3(s)
Which of the following pairs has about the same atomic radius?
Normally the alkaline earth carbonates (MCO3; M = Mg^2+, Ca^+2, Sr^+2, Ba+2) are insoluble in water. Why would the method used in this experiment work for calculating the molar mass of the alkaline earth? How would the calculations have to be cha..
