Bromine is a molecular compound Br2 and the intermolecular forces are london dispersion forces. Potassium chloride is an ionic compound forming a lattice with strong electrostatic forces holding the lattice together.
Less thermal energy is required to shake solid Br2 apart than that required for KCl
What else can I help you with?
What element has more electronegativity bromine or potassium?
Bromine has more electronegativity than potassium. Bromine is located in the halogen group of the periodic table, which tends to have high electronegativity values. Potassium, on the other hand, is a metal and typically has lower electronegativity values.
Does sodium have a higher melting point then potassium?
Yes, sodium has a higher melting point than potassium. Sodium has a melting point of 97.8°C while potassium's melting point is much lower at 63.38°C.
What has larger atomic radius potassium or bromine?
Potassium has a larger atomic radius compared to bromine. This is because atomic radius generally increases as you move down a group in the periodic table, and potassium is located in a lower group (Group 1) compared to bromine (Group 17).
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Calcium chloride is added to sodium chloride in the metallurgy of sodium because it helps lower the melting point of the mixture, making it easier to separate sodium metal from the molten mixture. This lower melting point allows for better efficiency in the electrolysis process.
Does bromine melt at a lower temperature than ethanol?
Yes, bromine melts at a lower temperature than ethanol. Bromine has a melting point of -7.2 degrees Celsius, while ethanol melts at -114 degrees Celsius.
Is the melting point of bromine higher or lower than the melting point of chlorine?
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
What element has more electronegativity bromine or potassium?
Bromine has more electronegativity than potassium. Bromine is located in the halogen group of the periodic table, which tends to have high electronegativity values. Potassium, on the other hand, is a metal and typically has lower electronegativity values.
Does rubidium have a higher melting point than potassium?
Yes, rubidium has a higher melting point than potassium. Rubidium has a melting point of 39.3°C, while potassium has a melting point of 63.4°C.
Does sodium have a higher melting point then potassium?
Yes, sodium has a higher melting point than potassium. Sodium has a melting point of 97.8°C while potassium's melting point is much lower at 63.38°C.
Why is water lower than the melting point of sodium chloride?
Sodium chloride is a ionic compound. Generally they have high melting points.
What has larger atomic radius potassium or bromine?
Potassium has a larger atomic radius compared to bromine. This is because atomic radius generally increases as you move down a group in the periodic table, and potassium is located in a lower group (Group 1) compared to bromine (Group 17).
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Calcium chloride is added to sodium chloride in the metallurgy of sodium because it helps lower the melting point of the mixture, making it easier to separate sodium metal from the molten mixture. This lower melting point allows for better efficiency in the electrolysis process.
Does bromine melt at a lower temperature than ethanol?
Yes, bromine melts at a lower temperature than ethanol. Bromine has a melting point of -7.2 degrees Celsius, while ethanol melts at -114 degrees Celsius.
Which element has a higher melting point potassium or calcium?
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
How do you separate ammonium chloride from a mixture of ammonium chloride and potassium chloride?
To separate ammonium chloride from a mixture of ammonium chloride and potassium chloride, you can use the process of sublimation. Ammonium chloride sublimes at a lower temperature compared to potassium chloride. By heating the mixture, the ammonium chloride will directly change from a solid to a gas, leaving behind the potassium chloride. The resulting gas can be condensed back into solid form for collection.
Does potassium have a higher atomic number than chlorine and a lower atomic number than bromine?
yes
How can you separate a mixture of ammonium chloride and potassium chloride?
A mixture of ammonium chloride and potassium chloride can be separated using the process of sublimation. You must also note that both these substances are sublimable. Well this technique is quite feasible in this case as the sublimable temperatures of ammonium and potassium chloride differ widely. Between the two, ammonium chloride has lower sublimable temperature. Therefore, it sublimes first followed by potassium chloride.
