24
Q

Significant figures

A

If there is a decimal, move from left to right and start with the first non zero number. Every number after that will be the amount of sig figs.

If there is no decimal move from right to left and start with the first non zero number and every number that comes after is sig figs.

25
Q

Density

A

D= m/v

Ex:
1 D = ? M=2.54. V= .382 mL
D= 2.54/.382
D= 6.65 g/cm3

26
Q

Physical change

A

Does not alter the composition or identity of a substance
Examples: sugar dissolving in water.
Breaking a pencil or paper

27
Q

Chemical Change

A

Alters composition or identity of a substance

Examples: burning wood
Hydrogen burns in air to form water.

28
Q

What are the seven families of the periodic table?

A 
Alkali metals
Alkaline earth metals 
Transition metals
Halogens
Noble gases 
Lanthanides 
Actinides
29
Q

Compounds

A

A substance composed of two or more elements chemically united to fixed proportions.
Ex: CO2
H2O

30
Q

Elements

A

A substance that cannot be separated into simpler substances by chemical means.
Ex: oxygen
Iron

31
Q

Ionic Compound

A

Any neutral compound containing cations and anions
Ex: Na2SO4
MgCO3

32
Q

Covalent compounds

A

Compounds containing only covalent bonds.
(Covalent bonds= a bond in which two electrons are shared by two atoms)

Ex:
S2CL4 (disulfur tetrachloride)
H2O6 (dihydrogen hexoxide)

33
Q

Acids

A

A substance that yields hydrogen ions (H+) when dissolved in water.
Ex:
HCL Hydrochloric acid (binary acid)
H3PO4 phosphoric acid (ternary acid)

34
Q

Bases

A

A substance that yields hydroxide ions (OH -) when dissolved in water
Ex:
NaOH

35
Q

Polyatomic ions

A

An ion that contains more than one atom

36

A

Nitrate

37

40
Q

ClO3 -1

A

Chlorate

41
Q

CrO3 -1

A

Chromate

42
Q

Atoms

A

The basic unit of an element that can enter into chemical combination

43
Q

Molar mass

A

The mass in grams or kilograms of 1 mole of atoms, molecules or other particles.

44
Q

Atomic mass

A

The mass of an atom in atomic mass units

45
Q

Molecular mass

A

The sum of the atomic weights of the atoms in the empirical formula of the compound

46
Q

Formula mass

A

The sum of the atomic weights of the atoms in the empirical formula of the compound.

47
Q

Molarity

A

The molar concentration or the number of moles per solute per liter of solution.

48
Q

Mass spectrometry

A

An analytical technique that produces spectra (singular- spectrum) of the masses of the atoms or molecules comprising a sample of material.

49
Q

How does mass spectrometry work?

A

It works by ionizing chemical compounds to generate charged molecules or mole fragments and measuring their mass to charge ratios.

50
Q

Limiting reactants

A

Substance that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent since the reaction cannot proceed further without it.

51
Q

Theoretical yield

A

Amount of product that would react if all the limiting reagent reacted.

52
Q

Empirical formula

A

Tells us which elements are present and the simplest whole number ratio of their atoms. Simplest chemical formula, must be whole numbers.

53
Q

Actual yield

A

The amount of product actually obtained from a reaction.

Almost always less than the theoretical yield

54
Q

Theoretical yield

A

The amount of product that would result if all the limiting reagent reacted.

It is the maximum obtainable yield predicted by the balance equation

55
Q

Percent yield formula

A

% yield= actual yield/theoretical yield x 100%

56
Q

Molecular formula

A

An expression showing the exact number of atoms of each element in a molecule.

To calculate the actual molecular formula, we must know its approximate molar mass and it’s empirical formula.

57
Q

Percent composition

A

The percent by mass of each element in a compound.

58
Q

Percent composition formula

A

((N x molar mass of element) / (molar mass of compound)) x 100
