Answer:
Discovery and Naming: The first evidence of helium was obtained on August 18th, 1868 by French astronomer Jules Janssen. While in Guntur, India, Janssen observed a solar eclipse through a prism, whereupon he noticed a bright yellow spectral line (at 587.49 nanometers) emanating from the chromosphere of the Sun.
Answer:
C3H7NO2
Explanation:
The chemical formula of Alanine is C3H7NO2 and it belongs to almost all food category because it is present in one food of each food category such as dairy products, meat, nuts, soy, and whole grains etc. Alanine is a nonessential amino acid means that it does not directly obtained from the diet but it can be produced by the body using raw materials present in the food.
Monkey is good and that is all their it to it
Answer:
Increasing London dispersion forces
Explanation:
The graph below shows that the boiling points increase smoothly as you go from CH₄ to PbH₄, that is, as the molecular mass increases.
The only intermolecular forces between the molecules are London dispersion forces.
These forces increase with increasing molecular mass because there more electrons that can be temporarily on one side of the molecule to induce a temporary dipole in a nearby molecule.
