What else can I help you with?
What would you expect to have a higher melting point sodium chloride or aluminum oxide?
Aluminum oxide would have a higher melting point than sodium chloride. This is because aluminum oxide has stronger bonds between its ions, resulting in a higher energy requirement to break these bonds compared to the weaker bonds in sodium chloride.
Which of the following could cause a physical change in a solid piece of sodium metal?
Heating the solid piece of sodium metal can cause a physical change by melting it into a liquid. Cooling the liquid sodium back to its solid state would also be a physical change.
What temperature would sodium melt with a bunson flame?
Sodium will melt at a temperature of 97.8°C when exposed to a Bunsen flame. This is because the melting point of sodium is relatively low compared to other metals. It is important to handle molten sodium with care due to its reactivity with water and air.
What metal can displace sodium metal from sodium chloride?
You could use potassium, rubidium or caesium. However, there is no practical reason why you would do this. You'd have to do it in the melt, which would be hazardous, as all these metals react with water.
Why melting point of NaCl is more than that of Na?
NaCl is almost entirely ionic--the sodium is found as positive sodium ions and the chloride as negative chloride ions. These array themselves in crystalline patterns of alternating positive and negative charges so that each charged ion is paired with nearby ions of the opposite charge. To convert such a crystalline solid to a liquid, in which ions can move about independently of other ions, requires a great deal of energy because the oppositely charged ions would be farther apart. In metallic sodium, the sodium atoms are uncharged and no extra energy is needed to pry charged pairs of particles apart. However, the outermost electrons in each sodium atom can interact with the electrons of other neutral sodium atoms and a little bit of energy is needed to overcome these attractive forces when melting sodium metal.
Which would you expect to have a higher melting point sodium chloride NaCI or aluminum oxide AI203?
The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.
What would you expect to have a higher melting point sodium chloride or aluminum oxide?
Aluminum oxide would have a higher melting point than sodium chloride. This is because aluminum oxide has stronger bonds between its ions, resulting in a higher energy requirement to break these bonds compared to the weaker bonds in sodium chloride.
Which of following solids would hae higher melting point AlO3 vs NaBr?
Aluminum oxide (Al2O3) would have a higher melting point than sodium bromide (NaBr). This is because aluminum and oxygen ions in Al2O3 are more strongly bonded through covalent bonds, while sodium and bromide ions in NaBr are held together by weaker ionic bonds. Stronger bonding requires more energy to break, resulting in a higher melting point.
Would caesium with water be more reactive thank the reaction of sodium with water?
Yes, I saw a demonstration of this on a video once...
At which temperatures would sodium chloride be a liquid?
The melting point of sodium chloride is 801 0C.
Which element would you expect to be located in group 1 in the periodic table?
The elements are: lithium, sodium, potassium, rubidium, caesium and francium.
Which substance would have a higher boiling point sodium chloride or water?
Sodium chloride has a higher boiling point.
Which of the following could cause a physical change in a solid piece of sodium metal?
Heating the solid piece of sodium metal can cause a physical change by melting it into a liquid. Cooling the liquid sodium back to its solid state would also be a physical change.
What temperature would sodium melt with a bunson flame?
Sodium will melt at a temperature of 97.8°C when exposed to a Bunsen flame. This is because the melting point of sodium is relatively low compared to other metals. It is important to handle molten sodium with care due to its reactivity with water and air.
What is the state of matter of cesium at room temperature?
Caesium is usually a solid, but it does have a low melting point, and that's 83 °F (28 °C). This means that if you had a vial of caesium in your hand, and you were in a warm room, the caesium would melt. Caesium is one of only five metals that is a liquid at or near room temperature. Wikipedia has additional information on caesium. You'll find a link to their post on this element just down below here.
How NACL helps in melting of ice?
Sodium chloride (salt) lowers the melting point of ice - so it turns back to water at a lower temperature that it would normally.
Would metals or non metals tend to have a higher melting point?
Tungsten has the highest melting point of the elements and it is a metal.
