Q/ One of the lecture demonstrations showed 8 ice cubesmelting on an aluminum block in the same time neededto melt one cube on a Styrofoam block. If an ice cubehas an average mass of 30.6 grams, and each starts at–10.0 °C, how much heat (in kJ) transferred through thealuminum block to melt all 8 cubes to H2O(l) at 0.0 °C?Show all work.

Research is being carried out on cellulose as a source of chemicals for the production of fibers, coatings, and plastics. Cellulose consists of long chains of glucose molecules (C6H1206), so for the purposes of modeling the reaction we can consider the conversion of glucose to formaldehyde (H2CO). 1st attempt See Periodic Table O See Hint Calculate the heat of reaction for the conversion of 1 mole of glucose into formaldehyde, given the following thermochemical data: H,CO(g) + O,(g) –→ co,(g) - H,0(g) AP comb = -572.9 kJ/mol 6C(s) + 6H, (g) + 30, () → C,H12Og(s) AH= -1274.4 kJ/mol [CG)+0,() co,(] AHF= -393.5 kJ/mol » H,0(g) AHf= -285.8 kJ/mol What is the AHxn for the reaction below? → GH,CO (g) kJ
