Write a hypothesis for Section 2 of the lab, which is about the effect of the angle of insolation on the amount of heat a material absorbs. Use the format "if . . . then . . . because . . ." and be sure to answer this part of the lesson question: "What factors influence the absorption of sunlight at Earth's surface?"

Determine the wavelength of the light absorbed when an electron in a hydrogen atom makes a transition from an orbital in the n=3 level to an orbital in the n=7 level.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

The element that has the greatest electronegativity is
