In 2008, Americans talked, viewed, and listened to media, excluding the workplace, for 1.3 trillion hours, an average of 11 hours per person per day. By 2012, total consumption had increased to 1.46 trillion hours, or an average 13.6 hours per person per day, representing a year over year growth rate of 5 percent.
A description of how to write the name for CaCl2 (Calcium chloride). First we determine whether CaCl2 is an ionic or molecular (covalent) compound using the periodic table. From the periodic table Ca is a metal and Cl is a nonmetal.Therefore CaCl2 is an ionic compound since it consists of a metal and nonmetal.Since CaCl2 is an ionic compound we name CaCl2 using the name for the metal (Ca) directly from the periodic table and then changing the element name Chlorine to Chloride.Therefor the name for CaCl2 is Calcium Chloride.ince CaCl2 is an ionic compound we name CaCl2 using the name for the metal (Ca) directly from the periodic table and then changing the element name Chlorine to Chloride. Therefor the name for CaCl2 is Calcium Chloride.
As a result, it is much easier to melt Cl 2 to form a liquid or boil it to form a gas, and Cl 2 is a gas at room temperature. The difference between ionic and covalent bonds also explains why aqueous solutions of ionic compounds conduct electricity, while aqueous solutions of covalent compounds do not. When a salt dissolves in water, the ions are released into solution.
