I forgot what quantum means to be honest, the Bohr model In atomic physics, the Bohr model or Rutherford–Bohr model, presented by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity. After the cubical model (1902), the plum pudding model (1904), the Saturnian model (1904), and the Rutherford model (1911) came the Rutherford–Bohr model or just Bohr model for short (1913). The improvement over the 1911 Rutherford model mainly concerned the new quantum physical interpretation.
Solution :
"Aldol" stands for the abbreviation, aldehyde and alcohol. When a ketone or an aldehyde's enolate reacts with the carbonyl of a molecule at the alpha carbon, under the acidic or basic conditions so as to obtained the ketone or β-hydroxy aldehyde, is known as an aldol reaction.
For the conversion of the aldol addition product of a 3-hydroxy-3-(4-nitrophenyl)-1-(2-pyridyl)-1-propanone to an aldol condensation product of (E)-3-(4-nitrophenyl)-1-(2-pyridyl)-1-propenone, the mechanism is given in the diagram a below :
Answer: Most polyatomic ions are -ate, related ions that have 1 fewer oxygen atom are -ite (must have at least 1 oxygen tho) and nonmetals are ide.
Explanation:
Answer:
1 Mole O₂ / 2 Mole H₂O
Explanation:
The balance chemical equation for the synthesis of water is as follow,
2 H₂ + O₂ → 2 H₂O
In this equation the moles are specified by the coefficients i.e.
2 moles of H₂ reacting with 1 mole of O₂
2 moles of H₂ producing 2 moles of H₂O
1 mole of O₂ producing 2 moles of H₂O
Hence the molar ratio for O₂ and H₂O can be written as,
1 Mole O₂ : 2 Mole H₂O
or,
1 Mole O₂ / 2 Mole H₂O
