The equation for the reaction is: C6H807 + 3NaOH → C6H5O Na3 + 3H20
The concentration of the sodium hydroxide was 0.102 mol/dm3
Concordant results are those within 0.10 cm of each other.
Calculate the concentration of the citric acid in mol/dm3
Use only the concordant results from Table 5 in your calculation.
You must show your working.

what does the table look like

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

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.
