A mixture of 0.050 mol of 7_1.gif, 0.025 mol of7_2.gif, and 0.050 mol of 7_3.gif is placed in a 1.0-L vessle. The following equilibrium is established: 7_4.gif At equilibrium [NO] = 0.031 M Calculate the equilibrium concentrations of 7_5.gif and 7_6.gif

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
