Complete the Lewis structure below of an organic molecule isolated from the South American plant, Austroeupatorium inulifolium. Using both the completed Lewis structure and only the concepts taught about the hybridization model, answer the next four (4) questions. How many atoms in the completed Lewis structure use hybrid orbitals with bond angles of approximately 120 o between them

In pqr m< p=60 m< q= 30 and m

All forces cause motion? true or false

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]
