Resource summary

Question 1

Question
What is an oxyanion?
Answer
  • any acid that contains hydrogen and an oxyanion
  • a chemical compound that contains two or more elements
  • a polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms
  • an atom or group of atoms with a positive or negative charge

Question 2

Question
What are the types of chemical bonds?
Answer
  • covalent
  • ionic
  • metallic
  • chemical
  • polyatomic

Question 3

Question
A cation has a negative charge and a anion has a positive charge
Answer
  • True
  • False

Question 4

Question
Check the bonds with the correct name and definition
Answer
  • ionic bond-a nonmetal and a metal or two metals
  • covalent bond-two nonmetals
  • ionic bond-two nonmetals or two metals
  • covalent bond-two metals or metalloids

Question 5

Question
An acid is a chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically corrosive. it has a PH less than 7
Answer
  • True
  • False

Question 6

Question
What are the two types of acids?
Answer
  • binary acid and oxyacid
  • tertiary acid and ionic acid

Question 7

Question
What is the difference between polyatomic ions and monatomic ions?
Answer
  • Polyatomic ions are made up of two or more atoms bonded together that acts as a single unit with a net charge Monatomic ions are formed from only one atom
  • There isn't a difference
  • Monatomic ions have more atoms than polyatomic ions

Question 8

Question
An ion is an atom or bonded group of atoms with a positive or negative charge
Answer
  • True
  • False

Question 9

Question
A chemical bond doesn't hold atoms together
Answer
  • True
  • False

Question 10

Question
What is the difference between a binary compound and a tertiary compound
Answer
  • a binary compound has two different elements while a tertiary compound has three
  • there isn't a difference
  • the number of atoms

Question 11

Question
Check the steps involved in naming binary acids
Answer
  • The first word has the prefix hydro-
  • The rest of the first word consists of a form of the root of the second element with the prefix -ic
  • the second word is acid
  • identify the oxyanion present
  • it the elements name ends with -ate replace it with -ic

Question 12

Question
The following steps are the steps for naming oxyacids: 1. Identify the oxyanion present 2. The first word of an oxyacid;s name consists of the root of the oxyanion present and the prefix per- or hypo- if it is part of the name and a suffix 3. If the oxyanion's name ends with -ate replace it with -ic, if it ends with -ite replace it with the suffix -ous 4. The second word of the name is always acid
Answer
  • True
  • False

Question 13

Question
Which of these is correct when naming binary ionic compounds?
Answer
  • it must be a metal and a nonmetal or two metals the total charge of the compound must equal zero use the CDR method use the stock system
  • the total charge of the compound doesn't matter the CDR method s only useful sometimes the rules apply to any compound
  • there are no rules or precautions
  • the stock system isn't relevant

Question 14

Question
The stock system is a type of nomenclature that uses roman numerals to indicate charge of a transition metal
Answer
  • True
  • False

Question 15

Question
Check all of the binary ionic naming rules
Answer
  • name the metal/cation by its elemental name
  • name the nonmetal/anion by its elemental name with the ending -ide
  • determine the charge of the metal and indicate it with a roman numeral

Question 16

Question
What are the binary ionic naming rules with transitional metals?
Answer
  • 1. name the metal/cation by its elemental name 2. determine the charge of the metal and indicate it with a roman numeral in parenthesis 3, name the nonmetal/anion by its elemental name with the suffix -ide
  • 1. name the metal/cation by its elemental name 2. name the nonmetal/anion by its elemental name with the suffix -ide
  • 1. name the metal/cation by its elemental name 2. name the polyatomic ion

Question 17

Question
The rules following are the rules for naming a polyatomic ion: 1. Name the metal/cation by its elemental name- if a transitional metal is present, use a roman numeral 2. name the polyatomic ion
Answer
  • True
  • False

Question 18

Question
Covalent compounds are made of two metals
Answer
  • True
  • False

Question 19

Question
What is unique about covalent bonds?
Answer
  • they have prefixes
  • they use roman numerals
  • they don't use suffixes

Question 20

Question
In covalent bonds, a prefix is used on the first element if there are 2+ atoms of that element present
Answer
  • True
  • False

Question 21

Question
In covalent bonds, a prefix on the second element is not essential
Answer
  • True
  • False

Question 22

Question
You can reduce in covalent compounds
Answer
  • True
  • False

Question 23

Question
Check all the rules that apply to naming covalent compounds
Answer
  • The first element in the formula is always named first, using the entire element name
  • The second element in a formula is named using its root and the suffix -ide
  • Prefixes are used to indicate the number of atoms of each element that are present in the compound
  • The rules that apply to ionic bonds apply to naming covalent bonds
  • The elements can be out in whatever order you like

Question 24

Question
Which one below is Aluminum Phosphate
Answer
  • AlPO4
  • AlPO3
  • Al3(PO4)3
