Unformatted text preview: kadamati (skk558) – Post-lab 8 – Lyon – (52735) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Consider the following specific heats: cop- per, 0.384 J/g · ◦ C; lead, 0.159 J/g · ◦ C; water, 4.18 J/g · ◦ C; glass, 0.502 J/g · ◦ C. If the same amount of heat is added to identical masses of each of these substances, which substance at- tains the highest temperature? (Assume that they all have the same initial temperature.) 1. lead 2. copper 3. glass 4. water 002 10.0 points Given the following thermodynamic data, 2H 2 O(g) → O 2 (g) + 2H 2 (g) ΔH rxn = 483 . 6kJ H 2 O(g) → H 2 O(l) ΔH rxn =- 44 . 0kJ What is the molar heat of formation for liquid water, H 2 O (l)? Answer in units of kJ / mole. 003 10.0 points When fuels are burned in the presence of limited oxygen, carbon monoxide is formed....
