CaO has a double bond since there is a transfer of two electrons from the calcium to the oxygen. NaCl only has a single bond. Also, the EN difference between Ca and O is greater compared to that of Na and Cl. This means there is a greater dipole-dipole force (polarity) present. Basically, it has a stronger attraction between its cations and anions.
The compound is called calcium chloride. It is composed of Ca2+ cations and Cl– anions; those ions are stable since they have filled valence shells. Its ionic formula is written as CaCl2, the neutral combination of these ions.
Melting points: KCl: 770oC HCl: -114.22oC
Boiling point 58.78°C Melting point 7.2°C
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.
Yes, elements have fixed melting points; but some exceptions are with the elements having allotropes (as carbon, sulfur, phosphorous, etc.) - each allotrope has a specific melting point.
The melting point of NaCl is very different from the melting points of Na or Cl.
chloride isn't a thing on its own and the melting and boiling points of chlorine and magnesium will have no effect on the boiling and melting point og magnesium chloride.
Sodium chloride is a ionic compound. Generally they have high melting points.
Different proteins have different melting points.
No it is a solid. Calcium has a high melting point. Most metals (except mercury) have high melting points.
The melting point of sodium chloride is 801 0C. The boiling point of sodium chloride is 1 413 0C.
The melting point of sodium chloride is 801 0C. The boiling point of sodium chloride is 1 413 0C.
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
Melting and boiling points are different for each compound or element.
different levels of saturation, the more saturated the higher the melting point.
No. The melting and boiling points of liquids vary considerably.
There are hundreds of different glues, with different melting points, setting times and means of adhesion.
