A

Calculating mass

32
Q

Mass divided by density.

A

Calculating volume

33
Q

Used to compare the weight of an object to an equal weight of water (=1)

  • Density is used to calculate this
  • Substances that have this greater than 1 are more dense than water.
  • Substances that have this less than 1 are less dense than water.

A

Energy (usually in the form of heat)

40
Q

The temperature that a solid melts at.

A

Melting point

41
Q

The temperature that liquid boils at.

A

Boiling point

42
Q

Amount of heat necessary to turn 1gm og a solid into 1gm of liquid at the substance’s melting point.

A

Heat of fusion

43
Q

Amount of heat necessary to turn 1gm of liquid into a gaseous state at the substance’s boiling point.

A

Heat of vaporization

44
Q

A reaction where heat is removed and liberated (or radiated).

-liquid => solid + heat

A

Exothermic

45
Q

A reaction where heat is absorbed.

Mixture

53
Q

Composed of protons (+) and neutrons (0). When you add the protons and neutrons, you get the atomic mass.

Uncharged atom

58
Q

Each proton and neutron has a mass of this.

A

1 atomic mass unit (amu)

59
Q

The same atom, same number of protons and electrons, but the number of neutrons have changed (therefore having a different atomic mass).

PET scan

62
Q

If you change the number of electrons, but the number of neutrons and protons remains the same.

  • Losing an e = positive charge
  • Gaining an e = negative charge
A

Ions

63
Q
  • The dense nucleus rarely gets close enough to another nucleus to react.
  • Are farther out and therefore dictate interactions (through electron shells)
  • The movement and configuration of these is determined by the shells.
A

Electrons

64
Q

Determined by the distance an electron is from the nucleus.

- the further from the nucleus, the more it has.

A
