A lens is an instrument that can combine and focus light to a single point. The diagram below shows many different colors of light entering a lens and focusing on Point X. Which of the following best describes the effect the lens has on Point X? (SC.7.P.10.1)A. Point X will appear to constantly change color. B. The light will combine to form white light at Point X. C. Some of the light will combine at Point X and make it appear darker .D. The lens will cause the light from Point X to reflect back as a different color.

Will give imagine you are given a mystery element. it is, however, a discovered and known element. you may perform a maximum of two observations or tests to determine its identity. time and money is critical, so you need to prioritize your tests. if you can get by with a single test, you get 100 super-geek points from your research lab team. pick your two tests, number them as #1 and #2, and justify why you think these two will certainly be enough (and why the first might well be enough all by itself.) the available tests are classification into metal, non-metal, or metalloid, count of valence electrons, count of electron shells, atomic radius (error range: +/- 1 pm), electronegativity (error range: +/- 0.1), first ionization energy (error range: +/- 10 kj/mole), melting point (error range: +/- 10 c), and boiling point (error range: +/- 20 c).
