In acidic aqueous solution, the purple complex ion Co(NH3)5Br2+ undergoes a slow reaction in which the bromide ion is replaced by a water molecule, yielding the pinkish-orange complex ion : Co(NH3)5(H2O)3+ Co(NH3)5Br2+Purple(aq)+H2O(l) → Co(NH3)5(H2O)3+Pinkish−orange(aq)+Br−(aq) The reaction is first order in Co(NH3)5Br2+, the rate constant at 25 ∘C is 6.3×10−6 s−1, and the initial concentration of Co(NH3)5Br2+ is 0.100 MM. What is its molarity after a reaction time of 19.0 h ? How many hours are required for 85 %% of the Co(NH3)5Br2+ to react?
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
