Which would be expected to have the higher boiling point, t-butyl alcohol (2-methyl-2-propanol) or n-butyl alcohol (1-butanol)?

1 answer:

3 0

I would imagine that n-butanol would have the higher boiling point because it has less branching and therefore stronger intermolecular forces between molecules.

Using de Broglie's equation, λ = h/mv which would have a larger wavelength, a slow-moving proton or a fast-moving golf ball? Exp

tatuchka [14]

Answer: Proton will have larger wavelength

Explanation:

$\lambda =\frac{h}{mv}$ (de-Broglie's equation)

$\lambda =\text{wavelenght of the particle}$

h= Planck constant

m= mass of the particle

v= velocity of the particle

As we can see from the de-Broglie's equation , that wavelength is inversely proportional to the product of mass into velocity of the object.

The wavelength of proton will be higher than that fast moving golf ball because mass of proton $(1.67 \times 10^{-24}g)$ is very small than that of the golf ball (45.93 g). Proton is moving at slow velocity and the golf ball is moving with fast velocity by which value of product of mass into velocity of proton will be lower than the value of product of mass into velocity of the golf ball which will result in larger value of wavelength of the proton.

10095 m/sec to mile/ sec. 1 km = 0.6214 mile

Anarel [89]

Answer:

Explanation:

to convert any value in miles per second to meters per second, just multiply the value in miles per second by the conversion factor 1609.344. So, 10095 miles per second times 1609.344 is equal to 1.625 × 107 meters per second.

Which of the following atoms contains the same number of neutrons as an atom of Calcium-40? (2 points) Select one: a. Potassium-

SVEN [57.7K]

First, let's find the number of neutrons in Calcium-40. to find the number of neutrons, you need to take the atomic mass minus atomic number

neutrons in Calcium---> 40 - 20 (atomic number) = 20 neutrons

potassium-40---> 40- 19= 21
scandium-44----> 44- 21= 23
argon-38---------> 38- 18= 20
chlorine-36------> 36- 17= 19

the answer is argon-38
