According to Arrhenius concept a base is one which can donate hydroxide ion in its aqueous solution.
Here NaOH is a base as it can donate OH-.
As NaOH is a strong base it will have very high dissociation constant.
Due to high dissociation constant if will almost completely dissociate into sodium ions and hydroxide ions.

Thus in a solution of NaOH we will expect the following two ions
Na^{+} + OH^{-}[/tex]
Answer:
b) 47ml
Explanation:
The beaker would look like this:
60 mL
50 mL
------- The bottom of the meniscus is here
40 mL
30 mL
So <u>we have between 40 and 50 mL</u>. There are 10 mL of "distance" between those two values, and three fourths of that difference is (10 * 3/4) 7.5 mL.
So <em>the volume is 47.5 mL</em>, but because the measurement instrument (the beaker) does not handle decimals, the value we should report is 47 mL.
Answer:
double covalent bond
Explanation:
Double covalent bond -
It is the type of interaction observed between two species , which share the electrons in order to attain stability , is referred to as covalent bond.
The shared electrons are referred to as the bonding pairs or the shared pairs .
Stability and completion of the octet is the driving force for the formation covalent bond.
The molecules of the organic compound usually shows this type bonding .
A double covalent bond is the one which have four shared pair of electrons , i.e. two covalent bonds.
Hence , from the question,
Oxygen is capable to show double covalent bond .
Answer:
B- The polarity of the molecules and hydrogen bonding between molecules.

Answer:
Independent
Explanation:
Independent Variable is the volume of the object. Dependent Variable is the mass of the object. So it
