Acids/Base - The pH of 0.750M sodium hypochlorite, NaClO, is 10.72. What is the pKb for this base?
General Chemistry - 1. What is the correct equilibrium constant expression for the Haber process (production of ammonia gas from nitrogen and hydrogen gases?
2. The equilibrium consant (kc) for the reaction below is?
NH4Hs(s) <-> NH3 (g) = H2S (g)
Thanks!!!
solubility - 1.) What volume of water is needed to completely dissolve 1g of AgBr in Liters?
2.) What is the water solubility of AgCl in gams per liter?
equilibrium - For the reaction below, the partial pressures of gases at equilibrium are as follows:
H2=7.1x10(exponent negative 5)atm, Cl2=2.5x10(exponent negative 6)atm, and HCl=3.0atm. What is the value of the equilibrium constant Kp?
H2(g)+Cl2(g) (equilibrium sign) 2HCl(g)
Acid - A buffer is prepared by adding 1.50x10(exponent 2)mL of 0.250M NaOH to 2.50x10(exponent 2)mL of 0.350M weak acid, HB. The solution is diluted to 1.00L. If the pH of the resulting solution is 5.55, what is the pKa of the weak acid?
