Which option explains how purple pigments make some flower petals purple? Purple pigment molecules absorb purple light. After absorbing the purple light, these molecules send part of their purple color out. Thus, the petals appear purple.

Purple pigments absorb all colors of light except purple. Purple light is reflected. The only light that arrives to a person’s eyes from the petal is purple.

Purple pigments absorb all colors of light, including purple. Purple is the base color of the flowers. When all colors of light are absorbed, the flowers look purple.

Purple pigments absorb purple color and reflect all other colors back. Because only purple light is kept in the purple pigment, it appears purple.

Use examples from the article to explain one positive and one negative effect that chemistry has had on society.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.

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.
