Estimate the pH and pOH values for the solutions with hydrochloric acid (HCl) molar concentration of (a) 3.2∙10 -3 mol /L and (b) 0.052 mol /L .Assume the acid is completely dissociated.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

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.
