The difference in composition between a weak base and its conjugate acid is
Svetach [21]
A weak Bronsted-Lowry base is a weak proton acceptor, where the proton is in the form of H+, so the conjugate acid formed contains one more H atom and an extra positive charge.
Hope this helps!

Why do substances with weak intermolecular forces form solids at low melting points?
Advocard [28]
To make any substance solid, molecules must come very close to each other. Substances with weak intermolecular forces have weak bonding. Hence to make their molecules come close to each other, we must provide low temperature.

What is the energy of a photon with:<br> a wavelength of 827 nm? What type of radiation is it?
xeze [42]

Explanation:

Given parameters:

 Wavelength of photon  = 827nm  = 827  x 10⁻⁹m

Unknown:

Energy of the photon = ?

Type of radiation = ?

Solution:

The energy of a photon can be derived using the expression below:

      E = \frac{h c}{wavelength}

h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s

c is the speed of light = 3 x 10⁸m/s

Insert the parameters and solve;

      E  = \frac{6.63 x 10^{-34} x 3 x 10^{8}  }{827x 10^{-9} }  

       E = 2.4 x 10⁻¹⁹J

Type of radiation:

Near infrared radiation
