Una just de intimidate me with maths, physics and chemistry. Freda, my irish cream, my crunchy crackers, my milky chocolate, hope u are seeing them

RobinHez:
Ok...my turn!
Is Air a mixture or a compound?
Why?

Compound.

Contains elements that can't be easily separated. I get am?

My bad, I saw water instead

mattdasalt:
Which of these is not a part of the feather of
a bird?
A. Wing
B. aftershaft
C. Inferior umblilicus
D. Vane
E. Barbule

A

mattdasalt:
Option E pecking is correct

Ansa should be bopping. Birds peck

Zedric:
Compound.

because say e cheap u rush answer

I'm in dear need of glasses...u said compound
Nope! Its a mixture sorry.

Air is a mixture because it does not have a chemical formulae and it composition varies from place to place.

Zedric:
A

I second Ur answer but the questionnaire gave a different answer.

Abeg oooo.any mech engine in d house

Zedric:
A

inferior umbilicus is not a feather.
wing is the flight feather.

Its a mixture cus it does nt have a chemical formula,also cus it is a combination of different elements namely nitrogen,oxygen,smoke,noble gases etc.....tankxx 4 reading

Yes sister! U're absolutely right.

Absolutely!

Sorry about that error...u know how our brains work sometimes...I didn't read it well

Sorry all...a self acclaimed chemistry Rambo almost got me down!

Lol,it wasn't Ur question ooh.

Hehehehehe,u no try ooo,it ain't a cmpd its a mixture,cos
1)it has no chemical frmla
2)its constituent elements can be separated by physical methods
3)its individual constituents/elements remain unchangd ie retain their chemical properties
there are morE,bt these few has so far refused 2 leave me

mattdasalt:
A vehicle moves with constant acceleration in a
straight line.

A--------------B
its speeds at A and B are U and V
A--------------B
u v

respectively derive an expression for its
speed mid way btw A and B

A------C------B
u K v

(lets assume the mid way point C has a vel of K

RECALL V^2 = U^2 + 2AS
V^2 -U^2=2AS

FROM A TO C( U is the initial vel and K the final vel)
K^2- U^2= 2AS
FROM C TO B(K is the initial vel and Vthe final vel)
V^2 - K^2=2AS


I.E K^2-U^2= V^2-K^2
K^2+ K^2 =V^2+U^2

2K^2=V^2+U^2
K^2=(V^2+U^2)/2

K=√[V^2+U^2)/2

THEREFORE THE SPEED AT THE MID WAY OF A AND B IS √[(V^2+U^2)/2]

Nyc bro.....tnx

I think wing is actually the structure that serves as attachment for feathers and not a feather itself...Wings r modifies limbs remember *U can disprove it sha*.

OKAY thanks.

awayu pukka36...ave missed u..
ahhh God..tobiee ure matter dey heaven ohhhhh...lolz..

Wrong! Air is no compound...its a mixture

inferior umbilicus is not a feather.
wing is the flight feather.

Its part of the feather, sir. The feather is part of the wing and not vice versa, the answer is wing

U have it mixed up, its a compound. You could Google it

everyone is now afraid to claim Rambo...I guess my campaign against Ramboism is paying off.

Ayam fine,hw was Ur day?

Choi,abeg wetin be rambo? We r all learners here na...He should disprove with facts/points.

lol. I just say make I try my luck but I think its a compound. In fact, I know pure water is a compound.


A beg, I think say Na water
