Why ist necessary to rinse the clean burette before filling it with the unstandardised sodium hydroxide solution?
It is a rule of safety in chemistry: to remove any micro-drops of water from the pipette.
What is the rule of determining formula of chemical compounds?
The sum of the positive charge must equal to the sum of negative charge Ex. sodium chloride sodium=Na+ chloride=Cl- Formula=NaCl
Is sodium bisulfate soluble in water?
yes. sodium is always soluble. there are no exceptions to this rule.
Why you should not stir the mixture that is in the filter funnel in chemistry?
This is not a rule in laboratory.
Is magnesium sulfide a ionic or covalent compound?
It depends on the rule you use to classify it. Magnesium Sulfide is ionic, if using the metal-nonmetal rule. It is polar covalent, if using the 1.7 electronegativity difference rule. Both these rules are generalizations.
What is octet rule and give two examples which do not follow this rule?
The octet rule is a rule in chemistry where elements want to form bonds to attain 8 electrons in their valence shell. An example of this would be sodium chloride. Bonds that don't have 8 electrons in their valence shell don't follow this rule

Can a person with BSC.ED in chemistry do MSC in chemistry?
Depends on the university, but as a general rule -YES
What is the rule of shelter in chemistry?
to have a rest and to be comfortable
What is a zero-sum rule?
a rule that is used to help balance equations (used in chemistry)
Who is the inorganic chemistry?
Inorganic chemistry study compounds which not contain carbon (several exceptions to this rule exist).
What is the sodium content in lite salt?
A rule doesn't exist; approx. 30 %, as sodium.
Is sodium bisulfate soluble in water?
yes. sodium is always soluble. there are no exceptions to this rule.
