Which of the following is TRUE? -insoluble ionic compounds are strong electrolytes.
-the higher the temperature, the higher the solubility of a gas in a liquid.
-the more solute particles in solution, the greater the effect on freezing point and boiling point.
-strong acids that dissociate completely into ions are non-electrolytes.

catya your not at all which answer i've seen you do this on another question!

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
