A chemical that gives off hydrogen ions in water

41
Q

What are the Rules for naming acid compounds?

A

-ide is hydro- and -ic acid
-ate is -ic acid
-ite is -ous acid

42
Q

What are the Rules for naming molecules?

A
  1. Name first element with prefixes
    a) do not use mono in first element
    b) organic molecules with H or C
    dont use prefixes
  2. Change 2nd element to -ide
  3. Use prefixes for second element

SO2 is sulfur dioxide
SiI4 is silicon tetraiodide
SF6 is sulfur hexafluoride
CS2 is carbon disulfide

Q

What are the 6 Sig Fig rules

A

1) all nonzero digits are significant
2) zeros in the middle are significant
3) zeros at the beginning are NOT significant
4) zeros at the end are significant if there is a decimal point
5) in multiplication and division, answer can’t have more sig figs than the least original number
6) in addition and subtraction, answer cannot have more digits after decimal point than either original number

54
Q

What is an atomic number?

A

The number of protons in the nucleus of each atom

55
Q

What is the atomic mass number?

A

The total number of protons and neutrons of the atomic nucleus

56
Q

What is an isotope?

A

An atom of the same element that have the same number of protons but different number of neutrons changing the atomic mass of the element

57
Q

What is an atom?

A

The smallest identifiable unit of an element that consist of a nucleus (neutrons & protons) and electrons

58
Q

What is an atomic weight?

A

The weighted average of the atomic mass of all natural isotopes of an element

59
Q

What is the actual yield?

A

The amount of product obtained from lab data

60
Q

What is theoretical yield?

A

The amount of product obtained from stoichiometry calculations

61
Q

What is the formula for the percent yield?

A

Percent yield=actually yield/theoretical yield x 100%

62
Q

What is an empirical formula?

A

A compound that contains the smallest whole number mole to mole ratio of elements in that compound

Molecular formula- C2H6
Empirical formula- CH3

63
Q

Why is the molecular formula different from empirical formula?

A

It shows the actual number of atoms in each element of a molecule

64
Q
