2.21 Using Table 2.2, determine the number of covalent bonds that are possible for atoms of the following elements: germanium, phosphorus, selenium, and chlorine. 2.24 On the basis of the hydrogen bond, explain the anomalous behavior of water when it freezes. That is, why is there volume ...
determine the number of covalent bonds that are possible for atoms of the following elements: germanium, phosphorus, selenium, and chlorine. 2.24 On the basis of the hydrogen bond, explain the anomalous behavior of water when it freezes. That is, why is there volume expansion upon solidification...
Do this by adding together the molar mass of sodium, Na, and the molar mass of chlorine, Cl. The molar mass of Na = 22.99 g The molar mass of Cl = 35.45 g The molar mass of NaCl = 22.99 + 35.45 = 58.44 g 3 Multiply the mass of the solute by its molar mass conversion factor...
