  • tertiary acid and ionic acid

Explanation

Question 7 of 30

1

Select one of the following:

  • 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

Select one of the following:

  • True
  • False

Explanation

Question 9 of 30

1

A chemical bond doesn't hold atoms together

Select one of the following:

  • True
  • False

Explanation

Question 10 of 30

1

What is the difference between a binary compound and a tertiary compound

Select one of the following:

  • a binary compound has two different elements while a tertiary compound has three

  • there isn't a difference

  • the number of atoms

Explanation

Question 11 of 30

1

Check the steps involved in naming binary acids

Select one or more of the following:

  • 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

Explanation

Question 12 of 30

1

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

Select one of the following:

  • True
  • False

Explanation

Question 13 of 30

1

Which of these is correct when naming binary ionic compounds?

Select one of the following:

  • 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

Explanation

Question 14 of 30

1

The stock system is a type of nomenclature that uses roman numerals to indicate charge of a transition metal

Select one of the following:

  • True
  • False

Explanation
