Think of w shape with 4 sides the shape I know tat is Quadrilateral is a square
Explanation:
equations to note:
density= mass/volume
mass= volume *density
volume= mass/density
you have a volume- 8.33cm3
you have a density- 2.07 g/cm3
Answer:
8.33cm3 * 2.07g/cm3= 17.24g
mass= 17.24g
Answer:
33
Explanation:
The atomic number of an element configuration 2,8, 8,2,13 is 33.
The electron configuration is defined as the arrangement of electrons in atomic or molecular orbitals of an atom. The sum of electrons in different orbitals shown in the electron configuration represents the atomic number of the atom.
So, atomic number of the element configuration 2,8, 8,2,13 is 33.
<u>Answer:</u> The frequency of the light is
<u>Explanation:</u>
The equation used to calculate the energy for a transition, we use the equation:
where,
n = principal energy level
Calculating the energy difference:
To calculate the energy of the light for a given frequency, we use the equation given by Planck, which is:
where,
E = energy of the light =
h = Planck's constant =
= frequency of the light = ?
Putting values in above equation, we get:
Hence, the frequency of the light is
Answer:Free radical mono-halogenation of an alkane is typically conducted using bromine versus chlorine because the bromine radical is less reactive and therefore more selective.
Explanation: Halogenation occurs when a halogen replaces one or more hydrogen atoms in an organic compound ie chlorine or bromine with the reactivity of the halogens decreasing in the order of F2 > Cl2 > Br2 > I2
Since fluorine reacts explosively making it is difficult to control, and iodine is unreactive. Free radical mono-halogenation of an alkane is typically conducted using bromine versus chlorine with Chlorination ie chlorine radical being more reactive and not selective and the Bromination of alkanes ie bromine radical occurring similarly but slower and less reactive but more selective which is due to the fact that a bromine atom is less reactive in the hydrogen abstraction than a chlorine atom evidence in the higher bond energy of H-Cl than H-Br.
