Fill in the blank. As wavelength increases, energy (increases, decreases) .
The Heisenberg uncertainty principle says that it isn't possible to know for a particle simultaneously.
The stationary state with the lowest energy is called the .
Respond to the following based on your reading.

Explain why you don't notice that objects around you have a wavelength.
Describe the energy change when an electron moves from one energy level in an atom to another, both to a higher energy state and to a lower energy state. Tell whether a photon is absorbed or released in each case.
Match the term on the left with the best description on the right.

Term Description
6. Photon a. Having characteristics of both a wave and a particle

11. Wave-particle duality f. A particle of electromagnetic radiation

In which direction will the following reaction go if the standard reduction potentials are 0.80 v for ag/ag+ and –0.44 v for fe/fe2+? ag+ + fe → ag + fe2+ a.)forward b.)the reaction cannot occur. c.) not enough information is given. d.) reverse

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?
