Question

For reaction given Zn + Ag_2 O left arrow right arrow 2Ag + ZnO Identify element oxidized element reduced oxidizing agent reducing agent A sample of 0.050mol of NH_3 gas had a volume of 300mL. The temperature and pressure were held constant and some ammonia was removed to reduce the volume to 150mL. How many g of NH_3 were removed? (Molar mass of NH_3 = 17.03g/mol) Which of the following statements is TRUE? As pH goes up H_3 O^+ concentration goes down The pH of a 0.1M HCl solution is 0.1. A weaker acid dissociates more than a stronger acid OH^- is a Bronsted-Lowry acid Which of the following will have the weakest conjugate base? Explain your choice HSO_4^-, K_a= 1.2x10^-2 HCN,K_a = 4.9x10^-10 HF,K_a = 7.2x10^-4 NH_4^+, K_a = 5.6xl0^-10
