Plz im running out of ! ammonia (nh3) can be produced by the reaction of hydrogen gas with nitrogen gas: 3h2 + n2 → 2nh3 a chemist reacts 2.00 mol h2 with excess n2. the reaction yields 0.54 mol nh3. however, you calculate you should have recovered 1.33 moles nh3. what is the percent yield of the reaction? question options: (a)60% (b) 27% (c)41% (d)246%

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]
