What is the pH of a 1.24 mol/L solution of HCN(aq) if its Ka = 6.2 x 10-10? Rate my answer please For your understanding: HCN ⇌ H+ + CN-, Ka = 6.2x10^-10 = [H+]*[CN-]/[HCN] Notice the H+ and CN- ions are generated in pairs during HCN dissociation, hence [H+] = [CN-]. Hen...
I am doing a similar assignment as Anaa please help! y = 3cos(x-1) Amplitude: Period: Two x - intercepts: y-intercept: Domain: Range: Shift along x: Shift along y: Kind of reflection Thank you so much!
What is the percent ionization of a 1.38 mol/L weak acid if its Ka = 2.7 x 10^-6? Thanks again!
Find the temperature at which the reaction below is spontaneous given this data: Hf^o of NH3(g) = - 46 kJ/mol, S^o of NH3(g) = 192.5 J/mol·K, S^o of N2(g) = 191.5 J/mol·K, S^o of H2(g) = 130.6 J/mol·K. N2(g) + 3H2(g) <-----> 2NH3(g)
