Would the melting point of caesium be higher or lower then sodium?
Lower.
Sodium oxide melting point higher or lower than water?
Much higher. Water melts around 1 0C. At this temperature and much higher, sodium oxide is a solid.
How does IMF affect the boiling point or melting point of a substance?
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Because the mixture NaCl + CaCl2 has a lower melting point that NaCl.
Why is the melting point of oxygen lower than that of sodium?
Oxygen has weaker bonds between it's atoms compared to that of sodium which are obviously stronger
Does rubidium have a higher melting point than potassium?
LOWER
Would the melting point of caesium be higher or lower then sodium?
Lower.
Does salt have a higher or lower melting point than Na or Cl?
Common table salt (sodium chloride) has a much higher melting point than either sodium or chlorine.
Sodium oxide melting point higher or lower than water?
Much higher. Water melts around 1 0C. At this temperature and much higher, sodium oxide is a solid.
Do nonmetals have higher melting points or lower boiling points?
lower melting points
Why is water lower than the melting point of sodium chloride?
Sodium chloride is a ionic compound. Generally they have high melting points.
Is the temperature of the outer core higher or lower then the melting point?
higher
How does IMF affect the boiling point or melting point of a substance?
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
Is the temperature of the inner core higher or lower than its melting pointing?
higher
Is the temperature of the inner core higher or lower than its melting point?
higher
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Because the mixture NaCl + CaCl2 has a lower melting point that NaCl.
What is the standard state of rubidium?
At STP it is a soft shiny metal, which readily oxidises to rubidium oxide in the atmosphere. Since it is Group 1 pf the Periodic Table, it behaves like sodium or potassium . Since it 'lower' down the Group it reacts more vigorously that sodium or potassium .
