1What is an oxyanion?
- Aany acid that contains hydrogen and an oxyanion
- Ba chemical compound that contains two or more elements
- Ca polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms
- Dan atom or group of atoms with a positive or negative charge
2What are the types of chemical bonds?
- Acovalent
- Bionic
- Cmetallic
- Dchemical
- Epolyatomic
3A cation has a negative charge and a anion has a positive charge
- AVerdadeiro
- BFalso
4Check the bonds with the correct name and definition
- Aionic bond-a nonmetal and a metal or two metals
- Bcovalent bond-two nonmetals
- Cionic bond-two nonmetals or two metals
- Dcovalent bond-two metals or metalloids
5An acid is a chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically corrosive. it has a PH less than 7
- AVerdadeiro
- BFalso
6What are the two types of acids?
- Abinary acid and oxyacid
- Btertiary acid and ionic acid
7What is the difference between polyatomic ions and monatomic ions?
- APolyatomic 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 - BThere isn't a difference
- CMonatomic ions have more atoms than polyatomic ions
- APolyatomic ions are made up of two or more atoms bonded together that acts as a single unit with a net charge
8An ion is an atom or bonded group of atoms with a positive or negative charge
- AVerdadeiro
- BFalso
9A chemical bond doesn't hold atoms together
- AVerdadeiro
- BFalso
10What is the difference between a binary compound and a tertiary compound
- Aa binary compound has two different elements while a tertiary compound has three
- Bthere isn't a difference
- Cthe number of atoms
11Check the steps involved in naming binary acids
- AThe first word has the prefix hydro-
- BThe rest of the first word consists of a form of the root of the second element with the prefix -ic
- Cthe second word is acid
- Didentify the oxyanion present
- Eit the elements name ends with -ate replace it with -ic
12The 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- AVerdadeiro
- BFalso
13Which of these is correct when naming binary ionic compounds?
- Ait 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 - Bthe total charge of the compound doesn't matter
the CDR method s only useful sometimes
the rules apply to any compound - Cthere are no rules or precautions
- Dthe stock system isn't relevant
- Ait must be a metal and a nonmetal or two metals
14The stock system is a type of nomenclature that uses roman numerals to indicate charge of a transition metal
- AVerdadeiro
- BFalso
15Check all of the binary ionic naming rules
- Aname the metal/cation by its elemental name
- Bname the nonmetal/anion by its elemental name with the ending -ide
- Cdetermine the charge of the metal and indicate it with a roman numeral
16What are the binary ionic naming rules with transitional metals?
- A1. 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 - B1. name the metal/cation by its elemental name
2. name the nonmetal/anion by its elemental name with the suffix -ide - C1. name the metal/cation by its elemental name
2. name the polyatomic ion
- A1. name the metal/cation by its elemental name
17The 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- AVerdadeiro
- BFalso
18Covalent compounds are made of two metals
- AVerdadeiro
- BFalso
19What is unique about covalent bonds?
- Athey have prefixes
- Bthey use roman numerals
- Cthey don't use suffixes
20In covalent bonds, a prefix is used on the first element if there are 2+ atoms of that element present
- AVerdadeiro
- BFalso
21In covalent bonds, a prefix on the second element is not essential
- AVerdadeiro
- BFalso
22You can reduce in covalent compounds
- AVerdadeiro
- BFalso
23Check all the rules that apply to naming covalent compounds
- AThe first element in the formula is always named first, using the entire element name
- BThe second element in a formula is named using its root and the suffix -ide
- CPrefixes are used to indicate the number of atoms of each element that are present in the compound
- DThe rules that apply to ionic bonds apply to naming covalent bonds
- EThe elements can be out in whatever order you like
24Which one below is Aluminum Phosphate
- AAlPO4
- BAlPO3
- CAl3(PO4)3
25Check all the Polyatomic Ions
- ANH4
- BC2H3O2
- CSiO
- DBrO3
26Tartrate is C4H4O4
- AVerdadeiro
- BFalso
27Arsenate is AsO4
- AVerdadeiro
- BFalso
28Which of the following is Thiocynate?
- ASCN
- BCN
- COCN
- DTCN
29Dichromate is CrO4
- AVerdadeiro
- BFalso
