Target Reaction: 2CO2(g) + H2O(g) → C 2H2(g) + 5/2O2(g) Step Reactions: C2H2(g) + 2H2(g) → C2H6(g) ΔH = -94.5kJ H2O(g) → H2(g) + 1/2O2 (g) ΔH = 71.2 kJ 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g) ΔH =-566 kJ

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

In which phase(s) do the molecules take the shape of the container?

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]
