Molecular Compounds And Acids Section 6.5 Molecular Compounds And Acids

Binary Molecular Compounds Composed of two nonmetals, often times they combine in more than one way. Prefixes are used to tell the subscripts. The ending of the 2nd element is -ide

Table 6.5 Page 159

Write the names of the following. NO NO2 N2O N2O4 CO CO2 SO2 SO3

Naming Common Acids Acids are special compounds that produce H+ ions in solution. Usually H+ with an anion. Should know names and formulas of acids on page 160

Acids to Know Hydrochloric acid HCl Sulfuric acid H2SO4 Nitric acid HNO3 Acetic acid CH3COOH Phosphoric acid H3PO4 Carbonic acid H2CO3

Formula mass calculation To calculate formula mass in amu of compound. Count the number of each type of atom. Multiply the number by the average atomic mass of each type of atom. Example = Cr(NO2)3

What is the formula mass of the following? Cl2O7 HgBr2 (NH4)2SO4
