Questão 5
Questão
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
Questão 6
Questão
What are the two types of acids?
Questão 7
Questão
What is the difference between polyatomic ions and monatomic ions?
Responda
-
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
Questão 8
Questão
An ion is an atom or bonded group of atoms with a positive or negative charge
Questão 9
Questão
A chemical bond doesn't hold atoms together
Questão 10
Questão
What is the difference between a binary compound and a tertiary compound
Questão 11
Questão
Check the steps involved in naming binary acids
Responda
-
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
Questão 12
Questão
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
Questão 13
Questão
Which of these is correct when naming binary ionic compounds?
Responda
-
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
Questão 14
Questão
The stock system is a type of nomenclature that uses roman numerals to indicate charge of a transition metal
Questão 15
Questão
Check all of the binary ionic naming rules
Responda
-
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
Questão 16
Questão
What are the binary ionic naming rules with transitional metals?
Responda
-
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
Questão 17
Questão
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
Questão 18
Questão
Covalent compounds are made of two metals
Questão 19
Questão
What is unique about covalent bonds?
Responda
-
they have prefixes
-
they use roman numerals
-
they don't use suffixes
Questão 20
Questão
In covalent bonds, a prefix is used on the first element if there are 2+ atoms of that element present
Questão 21
Questão
In covalent bonds, a prefix on the second element is not essential
Questão 22
Questão
You can reduce in covalent compounds
Questão 23
Questão
Check all the rules that apply to naming covalent compounds
Responda
-
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
