Light can bounce off objects. This is called reflection and it's what allows us to see objects. This drawing shows a light wave reflecting from the red construction paper. Although many light waves are hitting the paper and reflecting from it, showing just one ray helps us follow the path of a single wave For each color of paper, which part of white light is reflected

(Colors of paper are red, blue, and green)

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Achemistry student needs of 40ml diethylamine for an experiment. by consulting the crc handbook of chemistry and physics, the student discovers that the density of diethylamine is 0.7 . calculate the mass of diethylamine the student should weigh out. round your answer to significant digits.
