Which of the following statements accurately differentiates an organic compound from an inorganic compound?

Proteins are organic molecules with

At 2600 K, ΔG° = 775 kJ for the vaporization of boron carbide:  B4C(s) ⇌ 4 B(g) + C(s)Find ΔG and determine if the process is spontaneous if the reaction vessel contains 4.00 mol B4C(s), 0.400 mol of C(s), and B(g) at a partial pressure of 1.0 × 10-5 atm. At this temperature, R T = 21.6 kJ.

A buffer solution is prepared by dissolving 0.200 mol of NaH2PO4 and 0.100 mol of NaOH in enough water to make 1.00 L of solution. What is the pH of the H2PO4-/HPO42- buffer if the Ka2 = 6.2 × 10-8?

Calculate the molar solubility of thallium(I) chloride in 0.20 M NaCl at 25°C. Ksp for TlCl is 1.7 × 10-4.

What is the pH of a buffer solution prepared by mixing 50.00 mL of 0.10 M NH3 with 25.00 mL of 0.10 M NH4Cl? Assume that the volume of the solutions are additive and that Kb = 1.8 × 10-5 for NH3.

In the shorthand notation for a galvanic cell, a double vertical line (∣∣) represents
