A mixture sample of 3.50 g containing Ag salt and Pb salt in the form of nitrates (AgNO3 and Pb(NO3)2), to analyze their mass percentage, we dissolve the mixture in water and prepare a 500 ml solution. Then we perform the following two separate analyses: Take 100 ml aliquot and add sufficient amount of Na2SO4 to form precipitates of Ag2SO4 and PbSO4, after cleaning, and dry out, the weight of precipitates is 0.577g Take 200 ml aliquot and add sufficient...

Consider the reaction C12H22O11(s)+12O2(g)→12CO2(g)+11H2O(l) in which 10.0 g of sucrose, C12H22O11, was burned in a bomb calorimeter with a heat capacity of 7.50 kJ/∘C. The temperature increase inside the calorimeter was found to be 22.0 ∘C. Calculate the change in internal energy, ΔE, for this reaction per mole of sucrose. Express the change in internal energy in kilojoules per mole to three significant figures.
