the number of atom present in the molecule is given by the Avogadro number that is 6.022×10²³ . For the CO2 , the molecule is made of 3 atom .So for the one mole of CO2 there are 1.8066×10²⁴ atom.
The melting point of the solid form of water, which is ice, is 0°C. When we convert both temperatures to kelvin by adding 273 to each we get the melting point of copper as 1357K and that of ice is 273K. Then, dividing the melting point of copper by the melting point of ice, both in absolute temperature scale. The answer would be 4.97. Thus, the energy of molecules of copper is approximately 5 times compared to that of water.
Answer:
See figure attached.
Explanation:
Pyridinium chlorochromate (PCC) is a weaker oxidizing agent when compared with oth chromic acid derivatives as dichromate, for example. This results in the fact that PCC wil oxidize a primary alcohol transforming it to a aldehyde.
The entire mechanism of the reaction of 1-butanol with PCC in an anhydrous solvent is shown in the figure attached.
The neutral intermediate and the organic product (1-butanal) are both represented in the figure.
