<span>Naphthalene has a higher melting point than biphenyl because naphthalene is a polar compound while biphenyl is a non-polar compound.</span> Studies show <span>that polar compounds have higher melting and boiling points than nonpolar compounds. It is because polar compounds have strong intermolecular forces.</span>
NaHCO₃ + HCl → NaCl + H₂O + CO₂
<u>Explanation:</u>
NaHCO₃ + HCl → NaCl + H₂O + CO₂
When Sodium bi carbonate (NaHCO₃) reacts with hydrochloric acid (HCl), it forms table salt (NaCl), water ( H₂O ) and Carbon di oxide (CO₂) gas is evolved.
Here base reacts with acid to form salt and it is the neutralization reaction.
As Bond energy is between carbon and oxygen the is 358 for a single bond of C-0 and 745 for a double bond is the c=0.
- In the first step the one atom pulls the electron from another atom
. In the second step that is forming bonds releases energy and is the exothermic
. In the third step they pull electrons away from other elements
.
- In the last step the additional bonds is needed more energy to make or break, so the bond energy is very higher Hence the -153.
Learn more about the energy between carbon and oxygen is 358.

The volume of this sapphire in cubic centimeters is 24.4 cm^3
We have the following information;
Mass of the Blue Giant = 486.52 carats
Density of the blue giant = 3.98 g/cm3
Volume of the blue giant = ?
Since the density is given in g/cm3, we must convert the mass to grams.
We have the conversion factor; 5
carats =
1
g
So;
If 5 carats make 1g
486.52 carats make 486.52 carats × 1g/ 5 carats
= 97.30 g
Since;
Density = mass/volume
Volume = Mass/Density
Volume = 97.30 g/3.98 g/cm3
Volume = 24.4 cm^3
