Q

Differentiate physical and chemical change.

A

In a nutshell, a chemical change produces a new substance, while a physical change does not. A material may change shapes or forms while undergoing a physical change, but no chemical reactions occur and no new compounds are produced.

Q

Enumerate Democritus and Leucippus’ five main principles about the atomic theory.

A
  1. Atoms cannot be seen by naked eyes.
  2. Atoms are in constant motion around an empty space called void.
  3. Atoms are completely solid.
  4. Atoms are uniform, with no internal structure.

29
Q

It is made by combining two or more parts; composed of or resulting from union of separate elements, ingredients, or parts.

A

Compounds

30
Q

Something made by combining two or more ingredients; a portion of matter consisting of two or more components in varying proportions that retain their own properties.

A

Mixtures

31
Q

It is made up of uniform structure or composition throughout.

A

Homogeneous

32
Q

Consisting of dissimilar or diverse ingredients or constituents.

A

Heterogeneous

33

45
Q

It is done by passing the liquid-solid mixture through a porous barrier such as filter paper or cloth.

A

Filtration

46
Q

It is used to separate a mixture of two or more liquids that boil or vaporize at different temperatures.

A

Distillation

47
Q

A long column is placed between the distilling flask and the condenser, as the vapors travel up the column, they condense, but they turn to vapor again as the column is heated by the rising vapors.

A

Fractional Distillation

48
Q

The simplest and most commonly used in laboratory experiments, paper is the stationary phase and a liquid such as acetone or alcohol is the moving phase.

A

Chromatography

49
Q

It is a technique used to separate compounds based on differences in solubility.

A

Extraction

50
Q

A substance that is strongly attracted to only one of the compounds of the mixture is added to the mixture.

A

Precipitation

51
Q

Separation through ____ is facilitated with the use of centrifuge, an apparatus where particles spin out very small particles out of a liquid or gas.

A

Sedimentation

52
Q

For mixtures of liquid and heavy insoluble solids. Example:
sand-water mixture - carried out by gently pouring the water out of the container after the sand has settled at the bottom of the container.

A

Decantation

53
Q

Free from mistakes or errors.

A

Accurate

54
Q

Very careful and exact about the details of something.

A

Precise

55
Q

Formula for volume

A

V = length x width x height

56
Q

Formula for density

A

Accuracy

59
Q

Refers to how closely individual measurements agree with each other.

A

Precision

60
Q

It depends more on the skill of the person making the measurement.
