6.hexa- 7.hepta- 8.octa- 9.nona- 10.deca-

Question 16

Hydrate

Answer 16

its a compound, often ionic, that contains one or more water molecules bound within its crystals in a fixed (stoichiometric) proportion

Question 17

anhydrous

Answer 17

Hydrates may typically be dehydrated by heating to remove the bound water molecules, yielding the anhydous compound

Question 18

to name hydrates

Answer 18

1. name the anhydrous compound (per usual rules)
2. add the word hydrate with a greek prefix denoting the number of water molecules

Question 19

Examples

CuSO4 -5H2O

CaCI-H2O

Answer 19

copper (||) sulfate pentahydrate

calcium chloride monohydrate

Question 20

Naming Binary Molecular Compounds

Answer 20

• the name of the more matallic element (the one farther to the left and/or bottom of the periodic table) is named first
• followed by the name of the more nonmetallic element (the one farther to the right and/or top) with its ending changed to the suffix -ide

Question 21

Naming binary molecular compound exceptions

Answer 21

• when only one atom of the first element is present, the prefix mono- is usually not used
• hydrogen binary compounds do not use any prefixes
• when two vowel are adjacent, the a in the greek prefix is usually dropped

Question 22

SO2

N2O4

P4O10

Answer 22

sulfur dioxide

dnitrogen tetraoxide

tetraphosphorus

Question 23

Naming Binary Acids

Answer 23

1. the word hydrogen is changed to the prefix hydro-
2. the other nonmetallic element name is moditfied by replacing -ide with -ic, and the words from and 2 are combined into a single word
3. the word acid is added as a word.

Question 24

H2S(g) H2S(aq)

Answer 24

hydrogen floride vs hydrofloric acid

hydrgen sulfid hydro sulferic acid

Question 25

Naming Oxyacids

Answer 25

1. omit hydrogen 2. start with the root name of the action 3. replace -ate with -ic, or -ite with -ous 4. add acid

Question 26
