Q: Answer the following question given this paragraph: Atoms or groups of atoms that carry an overall electrical charge are referred to as ions. Cations can be formed when a neutral species loses electrons, while anions are formed when a neutral species gains electrons. Q: What are atoms or groups of atoms called which carry and electrical charge? A:

OPTIONS:
- protons
- molecules
- electrons
- ions

A: ions

input: OPTIONS:
- reflected light
- polarized light
- diffracted light
- unpolarized light Now, answer this question: Answer the following question given this paragraph: 27.8 Polarization Polarization is the attribute that wave oscillations have a definite direction relative to the direction of propagation of the wave. EM waves are transverse waves that may be polarized. The direction of polarization is defined to be the direction parallel to the electric field of the EM wave. Unpolarized light is composed of many rays having random polarization directions. Light can be polarized by passing it through a polarizing filter or other polarizing material. The intensity I of polarized light after passing through a polarizing filter is I = I 0 cos 2 , where I 0 is the original intensity and is the angle between the direction of polarization and the axis of the filter. Polarization is also produced by reflection. Brewster's law states that reflected light will be completely polarized at the angle of reflection b , known as Brewster's angle, given by a statement known as Brewster's law: reflected light travel and. Q: What type of light is composed of many rays having random polarization directions? A:
A:
output: unpolarized light

Q: Answer the following question given this paragraph: Aldehydes and ketones can work weak hydrogen bonds with water through the carbonyl oxygen atom. The lower members of both series (3 carbons or fewer) are soluble in water in all proportions. As the length of the carbon chain increases, water solubility decreases. Similar to ethers, neither aldehydes nor ketones can hydrogen bond with themselves. As a result, their boiling points are generally lower than those of alcohols. Unlike alkanes however, aldehydes and ketones are polar molecules due to the more electronegative oxygen atom. The dipole-dipole interactions are stronger than the dispersion forces present in alkanes. The boiling points of aldehydes and ketones are intermediate between those of alkanes and alcohols. For example, the boiling point of ethane is -89C, ethanal is 20C, and ethanol is 78C. Q: Aldehydes and ketones can work weak hydrogen bonds with water through what atom? A:
Answer: carbonyl oxygen atom
