Green light has a wavelength of 550nm. What is the frequency of a photon of green light?
Vikki [24]

Answer:- Frequency is 5.4*10^1^4Hz .

Solution:- frequency and wavelength are inversely proportional to each other and the equation used is:

\nu =\frac{c}{\lambda }

where, \nu is frequency, c is speed of light and \lambda is the wavelength.

Speed of light is 3.0*10^8m/s .

We need to convert the wavelength from nm to m.

( 1nm=10^-^9m )

550nm(\frac{10^-^9m}{1nm})

= 5.5*10^-^7m

Now, let's plug in the values in the equation to calculate the frequency:

\nu =\frac{3.0*10^8m.s^-^1}{5.5*10^-^7m}

= 5.4*10^1^4s^-^1 or 5.4*10^1^4Hz

since, 1s^-^1=1Hz

So, the frequency of the green light photon is 5.4*10^1^4Hz .

Sliva [168]
  <span>From the balanced equation: 
4mol Fe will produce 2mol Fe2O3 
Molar mass Fe = 55.847g/mol 
16.7gFe = 16.7/55.847 = 0.3mol Fe 
This will produce 0.15mol Fe2O3 
Molar mass Fe2O3 = 159.6887 g/mol 
0.15mol = 159.6887*0.15 = 23.95g Fe2O3 produced
Hope this helps</span>

1st Define Covalent bond and it's type
irakobra [83]

Answer:

  1. COVELENT BOND:-The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond
  • SINGLE COVELENT BOND:-it is formed by sharing of one pair of electron between two atoms
  • DOUBLE COVELENT BOND:-it is formed by sharing of two pair of electron between two atoms
  • TRIPLE COVELENT BOND:- it us formed by sharing of three pair of electron beyween two atoms

2)Electron dot structures of carbon dioxide:-Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond. Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.

3))Sulfur has an atomic number is 16 with the

symbol as 'S'

  • The electronic configuration of sulfur is said to be 2,8,6
  • The valence electrons present in sulfur is 6.
  • Sulfur forms an octet structure by connecting 8 sulfur atoms with each other by the formation of single covalent bonds.
  • The sulfur molecule's chemical formula is S8.
  • Sulfur is usually used in the manufacture of sulphuric acid.
