Which formulas represent one ionic compound and one molecular compound
Answer: One atom is present in each of the elements hydrogen, carbon and nitrogen, respectively. Remember that the subscript 1 is understood when no subscript is mentioned. This formula points out that in one molecule of the compound, 18 carbon atoms, 21 hydrogen atoms, one nitrogen atom and three oxygen atoms are existent.An alternative way to writing a correct formula for an ionic compound is to use the crisscross method. In this method, the numerical value of each of the ion charges is crossed over to become the subscript of the other ion. Signs of the charges are dropped. Example 5.5. 2: The Crisscross Method for Lead (IV) Oxide.Figure 2.3. 4: (a) The white compound titanium (IV) oxide provides effective protection from the sun. (b) A crystal of titanium (IV) oxide, TiO 2, contains titanium and oxygen in a ratio of 1 to 2. The titanium atoms are gray and the oxygen atoms are red.

What is the main reason for this?, The main attractive force between polar molecules,in general, is, Which formulas represent one ionic compound and one molecular compound? and more.A molecular formula is a chemical formula of a molecular compound that shows the kinds and numbers of atoms present in a molecule of the compound. Ammonia is a compound of nitrogen and hydrogen as shown below: Figure 5.3. 1: The molecular formula for ammonia. NH3. There is one atom of nitrogen and 3 atoms of hydrogen in a …Naming Binary Molecular Compounds. Recall that a molecular formula shows the number of atoms of each element that a molecule contains. A molecule of water contains two hydrogen atoms and one oxygen atom, so its formula is \(\ce{H_2O}\). A molecule of octane, which is a component of gasoline, contains 8 atoms of carbon and 18 atoms of hydrogen.
