Greenhouse gases let through a lot (but not totally all) visible light, while infrared light gets trapped in, or reflected from, the medium. That means that although visible light is able to pass through to us on the surface, the long wavelength infrared light, which is produced as a result of this visible light heating up everything on Earth, gets trapped on its way out of the earth's atmosphere, heating up the planet.
A good analogy is the effect that a sunny day has on the inside of your car when you enter it. The light comes in, the heat stays in. The glass windows of the car display similar, although more intense, properties to greenhouse gases. Hence the name "GreenHouse Effect"
Answer: <span>C.) They reflect infrared light but let visible light pass through.

Answer:
b) 5.87 E23 molecules
Explanation:
∴ mm SO3 = 80.066 g/mol
⇒ molecules SO3 = (78.0 g)(mol/80.066 g)(6.022 E23 molec/mol)
⇒ molec SO3 = 5.866 E23 molecules SO3
A. The atmosphere
All the other examples are either elements or compounds, not mixtures. A mixture is a combination of elements that are not chemically or irreversibly conjoined so the atmosphere, made up of a variety of gases, would be a mixture.
Answer:
C) quartz
Explanation:
Quartz is a common mineral. Also, quartz isn't a metallic substance. I'm hoping that this helps :)
<span>Ionic bonding is the entire exchange of valence electron(s) between particles. It is a kind of substance security that creates two oppositely charged particles. In ionic bonds, the metal loses electrons to wind up plainly an emphatically charged cation, though the nonmetal acknowledges those electrons to end up noticeably a contrarily charged anion.</span>
