One mole of argon gas is held in a rigid container whose volume is 22.41 l at 273.15 k. 3.000 kj of heat is added. cv =12.47 j mol−1 k−1 a) what is the initial pressure of the gas? b) what is qsys? c) what is wsys? d) what is the final temperature of the gas? e) what is the final pressure of the gas? f) what is ∆e?

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]
