1. CHEMICAL FORMULA WRITING & NAMING OF COMPOUNDS

26. Write the chemical formula of the ionic compound that would form the elements: Aluminum and oxygen Mg and I Na and S Iron (II) and oxygen Na and polyatomic carbonate anion Ca and polyatomic nitrate anion Aluminum and sulfate anion

30. Write the chemical formula of the ionic compound that would form the elements: Na and polyatomic carbonate anion Ca and polyatomic nitrate anion Aluminum and sulfate anion

31. Acids are an important group of hydrogen- containing compounds. All BINARY acids or Nonoxyacids (Hydrogen + Nonmetal) 1. Starting with the prefix hydro- 2. Adding the root of the anion. 3. Adding the suffix –ic. 4. Using the word acid as the second name. Ex. HCl (aq) – hydrochloric acid

32. Acids are an important group of hydrogen- containing compounds. OXYACIDS (Hydrogen + Polyatomic ion) 1. Identify the polyatomic ion in the formula. 2. Change the suffix to –ous if it ends with an -ite. 3. Change the suffix to –ic if it ends in –ate. 4. Then, add the word “acid”. Ex. SO 3 - (sulfite) - H 2 SO 3 (aq) = Sulfurous acid SO 4 – (sulfate) – H 2 SO 4 (aq) = Sulfuric acid

33. Write the names or formulas of the following compounds 1. HBr 2. H 2 CO 3 3. H 2 SO 3 4. H 3 PO 4 5. HI 6. Sulfuric acid 7. Acetic acid 8. Chlorous acid 9. Dichromic acid 10. Nitric acid Hydrobromic acid Carbonic acid Sulfurous acid Phosphoric acid Hydroiodic acid H2SO4 CH3COOH HClO2 H2CrO4 HNO3

34. Just remember the rules.....

43. translate the statement balance the atoms specify states of matter adjust the coefficients check the atom balance
