The chemical equation that shows the reaction between nh3 and cuh206 is detailed as: [Cu(H2O)6]2+ (aq) + 2NH3(aq). —> [Cu(OH)2(H2O)4](s) + 2NH4 + (aq). the blue precipitate is Cu(OH)2(H2O)4 in which the blue color is caused by the Cu present in the solid.
The electronic configuration of Chlorine is 1s2 2s2 2p6 3s2 3p5.
There are three energy levels in chlorine
First energy level is n=1 has 1s2 so total 2 electrons
Second energy level is n=2, 2s2 2p6 so total 2+6= 8 electrons
Third has 3s2 3p5 electrons just 7 total... p can contain 6 electrons but only 5 are present. So the third level has lesser number of electrons than that can be filled
The function is known as the atomic orbital.
The electron is most likely to be found at a distance from the nucleus equal to the Bohr radius.
For Hydrogen,...
an electron in the ground state has the energy of -13.6eV.
This is relative to the ionization threshold.
Hoped this helped ;)<span />
when you hit a chemical with hammer and it was frozen only its physical properties will change and not he chemical properties,
when heated it may decompose to other chemical
when you hit with hamer it physical appearance will change but it remains chemically the same
when you put in salt solution , it wil interact with ions and its chemical properties changes
similarly when it was frozen, it retains its chemical properties.
Answer:
The correct option is:
D) 589.3 nm
Explanation:
Energy of one photon =
Hence, the wavelength (in nm) of radiation is 589.7nm (approximately equal to 589.3nm)
