The carbon monoxide, CO, in a 20.3 L sample was converted to carbon dioxide, CO2, by passing the gas over iodine pentoxide, I2O5, heated to 150C: 5 CO(g) + I2O5(s)  5 CO2(g) + I2(g) The iodine, I2, gas was collected in an absorber containing 8.25 mL of 0.01101 CM Na2S2O3: I2(g) + 2 S2O3 2(aq)  2 I(aq) + S4O6 2(aq) The excess Na2S2O3 was back-titrated with 2.16 mL of 0.00947 M I2 solution. What is the concentration of CO in the air sample in units of mg CO per liter

If a reactant was removed, did the new equilibrium system shift to make more reactants or more products?

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]
