Module 02 lecture assignment: hydrology a wetland has the following annual measurements (in cubic meters per year). what is the net annual change in water volume? what do you think is happening to the wetland over time? what could be causing this? 1. si 75 go 350 gi 25 et 25 so 50 a wetland has the following annual measurements (in cubic meters per year). what is the net annual change in water volume? what do you think is happening to the wetland over time? what could be causing this? 2. si 75 go 80 et 75 pn 15 so 45 gi 25

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]
