Hello, can someone please help me with this problem? I'm not
very good with Trig, so if you could show the work that'd be
great.
Thanks!
7. An airplane is flying in the direction E 32° (32), with airspeed of 875 km/h. Because of the wind, the resulting groundspeed and direction are 800 km/h and E 40° S or -40°. Find the direction and speed of the wind. (3 points)

Hey I got this question wrong on my physics test so if you could
help me find the right answer and describe how you got it that'd be
great. Thanks!

Please help me with this question! If you could explain your
answer and relate it to the HNMR shown on the right that would be
great. Thanks!
Draw the major product that results from the reaction below. Grignard, then condensation. HNMR is on the right with integrations in red. I'm pretty sure they're right this time. (2) MgBr We were unable to transcribe this image
I'm not sure if 4 is correct so I just wanted some
clarification, and for 5 I also am not sure as I need more
reasoning for why product B was formed!

I'm not sure which one is the correct answer, could someone tell
me which one it is and why
Which of the following pairs of substances can be used to make a buffer solution? а. HBr & LiOН b. NaC2H5COO & KHCOO C. H2SO4 & NaC6H5COO d. LIOH & KCH3COO e. HF & CeH5COOH
I really need a and e but if you could check and make sure my
answers are right for the other ones that would be great
thanks!
