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.
The electronegativity difference between carbon and oxygen is small. So they will form only covalent compounds and not ionic compounds. CO (carbon monoxide) and CO2 (carbon â¦ dioxide) are the two covalent compounds formed.In addition they can form ions like bicarbonate ion (HCO3-) and carbonate ion (CO32-) where there is covalent bond (and not ionic) between carbon and oxygen.onic bonds are formed when there is a strong difference between the electronegativity of the two atoms involved. Also, a metal is almost ALWAYS involved in ionic bonding. In fact, I can't think of any ionic compounds not involving metals.
