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.
This is true of the solid, Al atoms are surrounded by 6 Cl atoms, high coordination numbers are typical for ionic solids. In the vapour phase AlCl3 dimerises to form Al2Cl6 which is covalent, with chloride bridges-each aluminium has four chlorine atoms surrounding t. and achieves its octet.efinitely covalent. The electronegativity difference isn't great enough for a bond between Nitrogen and Oxygen to be ionic. In order for a bond to be Ionic, the electronegati â¦ vity difference must be 2.7 or greater. The electronegativity difference of N and O is merely .4.
