Answer:

By heating the mixture to maximum boiling point and then the solution is distilled at a constant temperature without having a change in composition.

Explanation:

An azeotropic mixture is also called a constant boiling mixture and it is a mixture of two or more liquids whose proportions cannot be altered by simple distillation due to the fact that when an azeotropic mixture is boiled, the vapor has the same proportions of constituents as the unboiled mixture.

Now, maximum boiling azeotropic mixture are the solutions with negative deviations that have an intermediate composition for which the vapor pressure of the solution is minimum and as a result, the boiling point is maximum. At that point, the solution will distill at a constant temperature without having a change in composition.

Radon-222 is a radioactive gas with a half-life of 3.82 days. How long would it take for fifteen-sixteenths of a sample of radon

Fittoniya [83]

Use the formula in terms of half life from the normal exponential functions

N(t) = N(0) (1/2) ^ (t/thalf) 

N(0) is the original quantity 

N(t) = quantity remaining at time t 

t is the time 


thalf is half life 

1/16 = (1/2)^(t/3.82) 

16 = 2^(t/3.82) 

4 = t/3.82 

t = 15.28 days

A schoolbus accelerates to 65 mph and enters the freeway. It travels

Inessa [10]

Answer:

Distance cover by school bus = 149.5 miles

Explanation:

Given:

Velocity of school bus = 65 mph

Time taken by school bus = 2.3 hours

Find:

Distance cover by school bus

Computation:

Distance cover = Velocity x Time taken

Distance cover by school bus = Velocity of school bus x Time taken by school bus

Distance cover by school bus = 65 x 2.3

Distance cover by school bus = 149.5 miles

Calculate the energy of one photon of yellow light that has a wavelength of 5.89x10^-7m.

Viktor [21]

Answer:

E = energy = ? ,

λ = Wavelength = 5.89 × 10^-7 m —> = 589 ×10 ^-9 m ,

h =Planck constant = 6.63 × 10^-34 J.s ,

f = frequency of photo/ electromagnetic radiation = c/λ ,

c = Speed of light in a vacuum = 3 × 10^8 m/s

___o___o____

$E = hf \\ \\ E = h \frac{c}{λ} \\ \\ E = 6.63 \times {10}^{ - 34} \frac{3 \times {10}^{8} }{5.89 \times {10}^{ - 7} } \\ \\E = \frac{6.63 \times {10}^{ - 34} \times 3 \times {10}^{8} }{5.89 \times {10}^{ - 7} } \\ \\ E = \frac{663 \times {10}^{ - 36} \times 3 \times {10}^{8} }{589 \times {10}^{ - 9} } \\ \\ E = \frac{1989 \times {10}^{ - 28} }{589 \times {10}^{ - 9} } \\ \\ E = 3.37691 \times {10}^{ - 19} J$
