I need some help with my homework and my lab report that are due tomorrow.
Calculations:1. Combine equations (2), (3) and (4) to obtain equation (1).Reaction 21. Calculate the change in temperature for reaction (2).2. Calculate the energy released (AH) in (2) (in J), using Q=mcAT (recall AH = -Q). Themass to be used is the mass of HCI. Assume the density of hydrochloric acid to be 1g/mL.3. Convert your answer into KJ4. How many moles of Mgo were used?5. Convert your answer into KJ/mol Mgo.Reaction 31. Calculate the change in temperature for reaction (3).2. Calculate the energy released (AH) in (3) (in J), using Q=mcAT. The mass to be used is themass of HCI.3. Convert your answer into KJ.4. How many moles of Mg were used?5. Convert your answer into KJ/mol Mg.6. Calculate the heat of reaction (1) in KJ/mol of Mgo by combining (2). (3) and (4) and their AHvalues that you obtained, in order to get equation (1) and its AH for the combustion of Mg.7. Determine the theoretical value for the combustion of magnesium, from the table of standardenthalpies of formation8. Calculate the percentage error.ConclusionBriefly state the results for the laboratory, in general.
