Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C(s)+O2(g)→2CO(g)   In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:   Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)   Write the net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide. Be sure your equation is balanced.

Mg + 2HCl → MgCl2 + H2 This experiment was performed two times. All values are valid to one decimal place. If the decimal place is not shown, add a ".0" Experiment Mass of Mg (mg) Starting Temperature (°C) Final Temperature (°C) 1 2 19.6 20.7 19.5 20.7 33 33.5 The previous page contained data from two experimental runs for the reaction between magnesium and hydrochloric acid. Mg+ 2HC! MgCl2 + H2 First, how many moles (n) of Mg reacted with the HCI? Use the average value of the two masses from your provided data set. Answer: 0.001658 I Mg + 2HCI MgCl2 + H2 Next, what is the amount of heat absorbed by the water (qsurr) in the experiment? Use the average AT from your data to calculate a single value for q. Report your answer in J. Remember to consult the lab manual and/or the video for any values you might need. Answer: Mg + 2HC! MgCl2 + H2 Finally, calculate A,H for this reaction and report your answer in kJ/mol. Answer:
