He proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another.

6kg of coal (carbon) is burned in air. What mass of carbon dioxide will be produced? (Assume that combustion is complete and ign
Flauer [41]

The mass of carbon dioxide that would be produced will be 22 kg

<h3>Combustion of carbon</h3>

The combustion of carbon in air can be represented by the equation:

C + O2 ---> CO2

The mole ratio of C to O2 to CO2 is 1:1:1.

Mole of 6kg of carbon = mass/molar mass

                                      = 6000/12

                                      = 500 moles

Equivalent mole of CO2 produced = 500 moles

Mass of 500 moles CO2 = mole x molar mass

                                          = 500 x 44.01

                                           = 22,005 g or 22 kg approximately

Identify what kind of ligand (weak or strong), what kind of wavelength (long or short), what kind of spin (high spin or low spin
Reptile [31]

Answer:

See explanation

Explanation:

Whether a ligand is strong or weak highly depends on its position in the spectrochemical series. Ligands that are found towards the left hand side of the series are weak field ligands while ions that occur towards the right hand side of the series are strong field ligands. The spectrochemical series is an arrangement of ligands in order of increasing magnitude of crystal field splitting.

Most of the strong field ligands have strong pi bonds and are capable producing greater crystal field splitting.

NH3, an and NO2 are all strong field ligands hence they produce long wavelengths and lead to the formation of diamagnetic complexes.
