At the onset of male puberty, which hormones promote the enlargement of the testes?

Which of the following pairs correctly identifies an example of an endocrine gland secretion and an exocrine gland secretion?

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.

Solid NaHCO3 is heated to 90°C. At equilibrium the total pressure of the gases produced is 0.545 atm. Calculate ΔG° at 90°C for the reaction2 NaHCO3(s) ⇌ Na2CO3(s) + H2O(g) + CO2(g).

Given: Ag+(aq) + e- → Ag(s) E° = +0.799 V AgI(s) + e- → Ag(s) + I-(aq) E° = -0.152 V Ni2+(aq) + 2 e- → Ni(s) E° = -0.267 V Which of the following reactions should be spontaneous under standard conditions? I. 2 AgI(s) + Ni(s) → 2 Ag(s) + 2 I-(aq) + Ni2+(aq) II. Ag+(aq) + I-(aq) → AgI(s)  

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

Calculate the equilibrium constant, K, at 25°C for the galvanic cell reaction shown below:8 H+(aq) + 5 Fe2+(aq) + MnO4-(aq)  →  Mn2+(aq) + 5 Fe3+(aq) + 4 H2O(l) For this reaction, E° = +0.74 V
