Answer:
(b) Both have the same number of valence electrons.
Step-by-step explanation:
We find the most striking chemical similarities between two Main Group elements when they are in the same Group of the Periodic Table.
Elements in the same Group have the same number of valence electrons.
(a) is <em>wrong</em>, because elements in the same group have <em>different masses</em>.
(c) is <em>wrong,</em> because atoms with the same number of protons belong to the s<em>ame element</em>.
(d) is wrong, because elements in the same Group must be in .
<em>different Periods.</em>
Explanation:
The given data is as follows.
(NaCl) =
(H-O=C-ONO) =
(HCl) =
Conductivity of monobasic acid is
Concentration = 0.01
Therefore, molar conductivity () of monobasic acid is calculated as follows.
=
=
=
Also, =
=
=
Relation between degree of dissociation and molar conductivity is as follows.
=
= 0.1254
Whereas relation between acid dissociation constant and degree of dissociation is as follows.
K =
Putting the values into the above formula we get the following.
K =
=
=
=
Hence, the acid dissociation constant is .
Also, relation between and is as follows.
=
= 3.7454
Therefore, value of is 3.7454.
The electromagnet and the permanent magnet -- interact with each other as any two magnets do. The positive end of the electromagnet is attracted to the negative pole of the permanent magnetic field, and the negative pole of the electromagnet is repelled by the permanent magnet's negative pole
Answer:
c) non polar Covalent
Explanation:
this is a molecule formed by atoms of the same element . they both have similar electronegativities and thus cancel out . This makes it a perfect Covalent molecule . The fact that it's a symmetrical molecule makes it non polar. a symmetrical molecule is a molecule formed by the overlap of orbitals of two atoms of the same element ( that is to say , there's no dipole )
A reaction rate is generally measured in terms of amount (usually in mass) per unit volume.
