Solubility and temperatures are directly related. The higher the temperature of the solvent, the higher the solubility of the solute in the solvent.
Dissolving a solute in a solvent is an endothermic process hence providing heat favors the process. Higher temperatures cause the molecules of the solvent to have high kinetic energy hence bombard each other and with that of the solute with high frequency. This then ensures fast diffusion of the solute particles in the solvent.
To get the number of formula units given 0.14 mg NaCl. We convert first the mass to moles by dividing by the molar mass, then multiplying by Avogadro's number. The final answer is 1.44 x 10^18 formula units.
The answer is that they were were not based on evidence and experiment and that made alchemy unscientific in its practices.
Alchemy is an old practice that might be thought of as a forerunner of chemistry.
The term alchemy is derived from the Arabic al-kimiyya, which is derived from Greek. Alchemy's fundamental notions focus around the transformation of one substance into another, often transforming a basic metal like lead or iron into a "noble" metal like silver or gold
The alchemist's main ambitions were to find the Stone of Knowledge, the medium of Eternal Youth and Health, and metal transmutation.
To conclude with we can say Alchemy is based on magic and occultism rather than true investigation and facts. Many of the items in it have been utilised as fundamentals for certain chemistry, although the vast majority of them are wrong and inaccurate.
