T Question 2 How Much Energy Would Be Required For The Production Of 1 0 Kg Of Hydrogen Gas Use The Thermochemical Equa 1 (102.4 KiB) Viewed 22 times

t Question 2 How much energy would be required for the production of 1.0 kg of hydrogen gas? Use the thermochemical equation in the previous Question 1 as the basis for the calculation. Round the answer to 2 significant digits with units of kJ 3.40000 KJ Hint: 1 kg is 1000 g of hydrogen gas. What is this amount in moles? Hint: the AH value in the thermochemical equation is per 3 moles of hydrogen gas produced, so the conversion factor must be written as (206 kJ / 3 mol H₂). Hint: when typing the answer, first round to two significant digits and then count the place-holding zeros carefully. Remember Blackboard does NOT recognize scientific notation, so you will have to type out all the zeros. Question 3 0/3 pts Kemmi Major does some experimental work on the combustion of sucrose: C12H22011(s) + 12 O₂(g) → 12 CO₂(g) + 11 H₂O(g) She burns a 0.05392 g pellet of sucrose in a bomb calorimeter with excess oxygen. She determines the 9rxn to be -916.6 J for the reaction. Calculate the AH value for the combustion reaction. (Round the answer to 3 significant digits, units of kJ, pay attention to positive or negative.) -5820.0 kJ/mol To answer this question, the mass of sucrose must be converted to moles. Then determine the AH value by dividing the qrxn value by the number of moles of sucrose reacted. Remember to change the units to kJ.
