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.
It is about in between ionic and polar bond in CaI2. Almost every, but not all, metals bonding to non-metals bond ionic, but if the difference of electronegativity (E.N.) is smaller than 1.2 than it tends to polar. covalent bond is a bond between two non-metallic elements. This means that they share electrons inside the molecules. OR A type of chemical bond in which there is mutual sha â¦ ring of electrons between two atoms is called covalent bond.
