A chemical that gives off hydrogen ions in water
41
What are the Rules for naming acid compounds?
-ide is hydro- and -ic acid
-ate is -ic acid
-ite is -ous acid
42
What are the Rules for naming molecules?
1. Name first element with prefixes

What are the 6 Sig Fig rules
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
What is an atomic number?
The number of protons in the nucleus of each atom
55
What is the atomic mass number?
The total number of protons and neutrons of the atomic nucleus
56
What is an isotope?
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
What is an atom?
The smallest identifiable unit of an element that consist of a nucleus (neutrons & protons) and electrons
58
What is an atomic weight?
The weighted average of the atomic mass of all natural isotopes of an element
59
What is the actual yield?
The amount of product obtained from lab data
60
What is theoretical yield?
The amount of product obtained from stoichiometry calculations
61
What is the formula for the percent yield?
Percent yield=actually yield/theoretical yield x 100%
62
What is an empirical formula?
A compound that contains the smallest whole number mole to mole ratio of elements in that compound
Molecular formula- C2H6
Empirical formula- CH3
63
Why is the molecular formula different from empirical formula?
It shows the actual number of atoms in each element of a molecule
64
What is the formula for solving a molecular formula?
X = molar mass of a substance/molar mass of empirical formula
