Answer:

The exosphere

Explanation:

In Earth atmosphere, the closer to the ground is the troposphere, then the stratosphere, then the mesosphere, in which the highest clouds and radar can reach. Then in the thermosphere, where the auroras and the satellites are form, the air glow starts to disappear until we reach the space in the last layer called exosphere.

The "exosphere" is the most distant and tenuous "layer" of our atmosphere.

The carbon-carbon (C―C) bond has an average bond energy of 347 kJ/mol, which is the energy required to break one mole of C―C bon

olganol [36]

Answer:

(3) 345 nm

Explanation:

Given:

Average C-C bond energy = 347 kJ/mol

To determine:

Wavelength of photon that can break a C-C bond

Calculation:

The energy (E) of a photon is related to its wavelength (λ) by the Planck's equation:

$E = \frac{hc}{\lambda }$

where h = Planck's constant = 6.626*10⁻³⁴ Js

c = speed of light = 3*10⁸ m/s

$\lambda = \frac{hc}{E}$

$\lambda =\frac{6.626*10^{-34}Js*3*10^{8}ms^{-1}*6.023*10^{23}mol^{-1}}{347,000Jmol^{-1}}$

λ = 3.45*10⁻⁷ m

Since 1 nanometer (nm) = 10⁻⁹ m

The calculated wavelength corresponds to 345 nm

Oil is more dense than water. How will this affect the weight of objects that will float on it?

horrorfan [7]

Oil is more dense than alcohol, but less dense than water. The molecules that make up the oil are larger than those that that make up water, so they cannot pack as tightly together as the water molecules can. They take up more space per unit area and are less dense.
