Metallic sodium and chlorine gas are produced by the electrolysis of molten sodium chloride.
<h3>What is a word equation?</h3>A word equation represents a chemical reaction using the names of the substances involved.
a) Word equation:
Sodium chloride + electrolysis → Sodium hydroxide + Hydrogen gas, Chlorine gas
b) The following reactions take place during the electrolysis of brine solution :
NaCl =
=
Now there are two cations and two anions which get discharged in the following way :
At cathode : =
At anode: =
The remaining ions
= NaOH
That's why we get ,
and NaOH.
c) Balance each equation is:
2NaCl (l) → 2Na(s) + (g)

Answer:-
Solution:- Wavelength is given and we are asked to calculate the frequency. The equation that correlates frequency with wavelength is:
where, is the symbol for frequency, c is the symbol for speed of light and
is the symbol for wavelength.
Speed of light is and the wavelength is given as
.
Let's plug in the values in the equation and so the calculations to calculate the frequency:
(since, )
So, the frequency of the wave is .
I am assuming that the compounds given are Pentane, 3-methyl-hexane, and 2, 4-dimethylpentane considering that the compounds were not separated by a comma.
_______________________________________________________
Pentane is in the form of a straight chain alkane. This is important as there are many isomers of Pentane, taking different shapes. By it's name it consists of 5 carbon atoms, and the number of hydrogen atoms should be 12, as the compound is nonpolar.
3-methylhexane is an alkane present in a hexane structure at position 3. There are thus 3 molecules at 3 ends of a hexane structure - H3C, CH3, and CH3
2,4-dimethylpentane is an alkane with respect to the formula [(H3C)2CH]2CH2.
With that information, refer to the three attachments below, for each compound given. They are in order -
