Can bees really fly if so why

Chemistry

Helga [31]3 years ago

The swirls of air at the edge of a bee's wing enable the insect to angle its wing more sharply toward the sky, improving the flow of air over the wing. It's this higher wing angle that gives bees, fruit flies and even humming birds enough lift to fly.

Water that freezes into ice,thaws back into water,and then freezes again in the cracks of rocks causes which type of weathering
alexandr402 [8]

Answer: A

Explanation: mechanical weathering  —Water gets into the cracks, freezes and expands making the cracks bigger. When there is thawing, the ice melts into water and more water gets into the rock. Freezing can happen again and the cracks get bigger.

Which is more acidic, 3-nitrophenol or 2-nitrophenol and why? Which is more basic, benzyl amine or aniline and why? Which is mor
Anika [276]

Answer:

2-nitrophenol is more acidic than 3-nitrophenol

benyl amine is more basic than aniline

dimethylamine is more basic than triethylamine

Explanation

Mesomeric effect stabilizes the anion formed when hydrogen of the  the -OH group in the 2-nitrophenol is lost. This mesomerism is most pronounced at the 2 and 4 position.

Stronger bases have more available lone pair of electrons. The lone pair of electrons in aniline is delocalized  over the ring. Hence it is unavailable for protonation while the lone pair on benzyl amine is available for protonation

Diethylamine is a stronger base because it has a balance of both inductive electron donation by alkyl groups, and solvation of the conjugate acid unlike triethylamine. Hence Diethylamine is a stronger base than triethylamine

A materials scientist has created an alloy containing aluminum, copper, and zinc, and wants to determine the percent composition
liubo4ka [24]

Answer:

0.8749 grams of hydrogen gas was formed from the reaction.

Explanation:

P = Pressure of hydrogen gad= 744 Torr = 0.98 atm

(1 atm = 760 Torr)

V = Volume of hydrogen gas= 11 L

n = number of moles of hydrogen gas= ?

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of vapor = 27.0 °C = 300.15 K

Putting values in above equation, we get:

Using an ideal gas equation:

PV=nRT

n=\frac{PV}{RT}=\frac{0.98 atm\times 11 L}{0.0821 L atm/mol K\times 300.15 K}

n = 0.4374 moles

Mass of 0.4374 moles of hydrogen gas:

0.4374 mol × 2 g/mol = 0.8749 g

0.8749 grams of hydrogen gas was formed from the reaction.
