It's proteins, (i took the the test and got an A) good luck hope this helps!!!
Answer:
Explanation:
2C₄H₁₀ + 13O₂ = 8 CO₂ + 10H₂O
Change in number of moles Δn = 18 - 15 = + 3 moles .
ΔHo = -2658.3 kJ/mol.
ΔHo = ΔEo+ Δn RT
Δn = 3
For one mole Δn = 1.5
ΔHo = ΔEo+ W
W = Δn RT
= 1.5 x 8.31 x 298
= 3714.5 J
= 3.7 kJ /mole
ΔHo = ΔEo+ W
ΔEo = ΔHo - W
= -2658.3 - 3.7 kJ
= - 2662 kJ .
Answer:
Preparation. Copper(I) iodide can be prepared by heating iodine and copper in concentrated hydriodic acid, HI. In the laboratory however, copper(I) iodide is prepared by simply mixing an aqueous solution of potassium iodide and a soluble copper(II) salt such copper sulfate.
