Colour arises due to partially filled d-orbitals. D-orbitals are split into two sub-orbitals with slightly different energies. When an electron in the lower energy d sub-orbital absorbs light, it moves up...

Firstly, we need to write a balanced equation for the oxidation of Fe²⁺ to Fe³⁺ . We know that when something is oxidised, it is losing electrons, making the half equation: Fe^2+...

3-bromo 3 methyl pentane will be the major product while 1 bromo 3 methyl pentane will be the minor. This is due to a more stable carbocation being formed. A secondary carbocation is more stable than a pr...

Options:A: 50cm^3, 54 degrees celsius, 1.0x10^5 Pa B: 50cm^3, 327 degrees celsius, 1.0x10^5 PaC: 100cm^3, 54 degrees celsius, 2.0x10^5 PaD: 100cm^3, 327 degrees celsius, 2.0x10^5 Pa
The equation to u...

Between the carbon layers in graphite there are van der waal forces which are very weak. Therefore, the layers of carbon atoms are able to slide over each other allowing graphite to be used as a lubricant...
