It's B Covalent.Now I'll add more words since the thing says I need to write at least 20 characters.
Explanation:
Anisotropy is the property of being directionally dependent, which implies different properties in different directions, as opposed to isotropyAn example of anisotropy is light coming through a polarizer. Another is wood, which is easier to split along its grain than across it.
Answer:
120mph
Explanation:
Google
divide the speed value by 1.467
or
176 times 60 second in a minute times 60 minutes in an hour
than divide by 5280 the amount of feet in a mile
Answer:
1350 g
Explanation: just add a 0
Answer:
344 nm is the longest wavelength of radiation with enough energy to break carbon-carbon bonds.
Explanation:
,ΔH = 348 kJ/mol
Energy required to break 1 mole of C-C bond = 348 kJ
Energy required to break 1 C-C bond = E
![E = \frac{348,000J}{6.022\times 10^{23}}=5.779\times 10^{-19} J](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B348%2C000J%7D%7B6.022%5Ctimes%2010%5E%7B23%7D%7D%3D5.779%5Ctimes%2010%5E%7B-19%7D%20J)
Energy related with the wavelength of light is given by Planck's equation:
![E=\frac{hc}{\lambda }](https://tex.z-dn.net/?f=E%3D%5Cfrac%7Bhc%7D%7B%5Clambda%20%7D)
![\lambda =\frac{hc}{E}](https://tex.z-dn.net/?f=%5Clambda%20%3D%5Cfrac%7Bhc%7D%7BE%7D)
![=\frac{6.626\times 10^{-34} Js\times 3\times 10^8 m/s}{5.779\times 10^{-19} J}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B6.626%5Ctimes%2010%5E%7B-34%7D%20Js%5Ctimes%203%5Ctimes%2010%5E8%20m%2Fs%7D%7B5.779%5Ctimes%2010%5E%7B-19%7D%20J%7D)
![\lambda =3.44\times 10^{-7} m = 344 nm](https://tex.z-dn.net/?f=%5Clambda%20%3D3.44%5Ctimes%2010%5E%7B-7%7D%20m%20%3D%20344%20nm)
![1 m =10^9 nm](https://tex.z-dn.net/?f=1%20m%20%3D10%5E9%20nm)
344 nm is the longest wavelength of radiation with enough energy to break carbon-carbon bonds.
