Why is an electrical double laver called a "double layer. draw a potential energy vs distance diagram, and explain the features ofa double layerf descaibe the physical significance of the debye-huckel parameterx how does it vary with the bulk concentration for a 1: 1, or 1: 2 electrolyte?

Identify a specific example for each type of technology

Determine the reaction and balance the following equations urgent due in the morning

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]
