The question makes no sense - you can't consider two variables at once - energy and mass. Most energy for the same mass - hydrogen.

Is uva radiation the lowest?

UV-A contains the least radiation (or energy) and is therefore, the least harmful. UV-C contains the most amount of energy and is the most harmful.


How does the level of an energy pyramid compare to the bottom level of that energy pyramid?

it contains the least amount of the total energy.


What happens to hydrogen at very high temperatures?

They are fused into helium and create energy. But it takes 4 hydrogen atoms to make 1 atom of helium. The Hydrogen is first converted to Deuterium (heavy hydrogen), and the two deuterium atoms fuse to make the Helium atom. This process releases a lot of energy, not the least because of the neutrons released. Lol


What 2 macromolecules store energy in carbon hydrogen bonds?

Hydrogen bonding found in macromolecules in living things (from the most to the least):DNAproteinscellulose (plants)ureaammonia


To maximize equilibrium yield of methanol would you use high or low temperature?

High because a higher pressure is the result of decreased volume and when a decreased volume for the equilibrium mixture is involved, the shift is toward the side with the least amount of mols of gas. 3 for reactants and 1 for methanol so towards methanol
