Molecules are made of atoms. Cells are made by a multitude of molecules. ... So cells are made of molecules and, consequently of atoms .
Robinson Annulation reaction is mainly done for the synthesis of six membered rings. This reaction is the combination of two reactions
1). Michael Addition Reaction and
2). Aldole Condensation.
The synthesis of <span>
desoxy-19-nortestosterone by Robinson Annulation is shown below,</span>
Answer:
Dear, your answer is
solubility is affected by current concentration, mechanical disturbance, temperature and pressure. So the answers are:
- Increasing temperature decreases the solubility of gases.
- Stirring increases the solubility of solids.
- Increasing pressure increases the solubility of gases.
- Decreasing the amount of solvent decreases the solubility of solids, liquids, and gases.
I would say the correct answer would probably be that to explain the approx 100 years between Dalton (early 1800's) atomic theory and JJ Thomson's discovery of the smaller particle the electron was that Thomson had the use of a cathode ray tube that helped to determine the existence of negatively charged particles about 2000 times lighter than a hydrogen atom and therefore a smaller particle than the atom. The cathode ray tube was not invented until 1897, when Thomson began experimenting with it.
Kinetic energy
That should be the answer
