Naming chemical compounds

1. Study Guide (Chapter 7: Covalent Compounds)
For each statement below, write true or false. If the statement is false, change the italicized word or words
to make it true (write the new word or words between parentheses at the end of the sentence):
1. ___ The sum of the oxidation numbers of all elements in a chemical formula is equal zero.
2. ___ In general, the chemical formulas which contain hydrogen (H) at the beginning represent acids.
3. ___ Binary acids do not have oxygen atoms in their molecules.
4. ___ The second element in the formula of a binary compound is named using the suffix -ite.
5. ___ The prefix tetra- indicates three atoms.
6. ___ The prefix hexa- indicates six atoms.
7. ___ In naming the first element in a formula, the prefix mono- is not used.
8. ___ For binary acids, the hydrogen part of the compound is named using the prefix hydro-.
9. ___ An oxyacid contains only two elements.
10. ___ If the name of the anion of an oxyacid ends in -ate, the acid name contains the suffix -ous.
11. ___ Molecular binary covalent compounds have a high melting and boiling point.
12. ___ Network solids are extremely hard solids.
13. ___ Hydrogen Bond is the strongest attraction force between molecules.
14. ___ Nonpolar molecules show dipole-dipole interaction between them.
15. ___ Sulfuric acid is the correct name for H2S(aq).
16.___ The name of PCl3 is potassium trichloride.
