Calcium oxide (CaO) and sodium chloride (NaCl) have different melting points due to differences in their bonding structures. Calcium oxide has an ionic bond, where calcium ions are attracted to oxide ions, requiring more energy to break these strong bonds compared to the ionic bonds in sodium chloride. Sodium chloride has a higher melting point due to its stronger ionic bonds and the smaller size of the chloride ion compared to the oxide ion in calcium oxide.
What else can I help you with?
Do All minerals have the same melting point True of False?
False, all minerals DO NOT have the same melting point
Which has higher melting point KCl or HCI?
KCl (potassium chloride) has a higher melting point compared to HCl (hydrogen chloride). This is because KCl is an ionic compound with strong electrostatic forces between ions, whereas HCl is a covalent molecule with weaker intermolecular forces.
what is the formula for the compound formed by calcium ion and chloride ions?
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.
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
Which property of calcium oxide does the lattice structure explain?
Oh, dude, the lattice structure of calcium oxide explains its high melting and boiling points. Like, the atoms are all arranged in a super organized way, making it harder for them to break apart when you try to heat them up. So yeah, if you're ever wondering why calcium oxide is so stubborn about turning into a liquid or gas, you can blame it on the lattice structure.
What is a property of sodium chloride that is not a property of sodium or chloride?
The melting point of NaCl is very different from the melting points of Na or Cl.
What the melting point of chloride?
Chloride is not substance that can be isolated but an negative ion that needs to have its charge balanced by a positive ion. Compounds containing this ion are called chlorides, their melting points vary.The element chlorine has a melting point of -101. 5 degrees Celsius, which is equivalent to 171.6 Kelvin and -150.7 degrees Fahrenheit.
Why is water lower than the melting point of sodium chloride?
Sodium chloride is a ionic compound. Generally they have high melting points.
Do proteins have definite melting points?
Different proteins have different melting points.
Is calcium liquid at room temperature?
No it is a solid. Calcium has a high melting point. Most metals (except mercury) have high melting points.
What are the three elements that have lower melting points than calcium?
The three elements that have lower melting points than calcium (which has a melting point of about 842°C) are sodium (melting point 97.8°C), potassium (melting point 63.5°C), and magnesium (melting point 650°C). Sodium and potassium are alkali metals, known for their low melting points, while magnesium, though a metal, also has a relatively lower melting point compared to calcium.
What are the melting and boiling points of sodium cloride?
The melting point of sodium chloride is 801 0C. The boiling point of sodium chloride is 1 413 0C.
How Calcium chloride are the particles held together and arranged in the solid?
In solid calcium chloride (CaCl₂), the particles are held together by strong ionic bonds between calcium ions (Ca²⁺) and chloride ions (Cl⁻). These ions arrange themselves in a crystalline lattice structure, where each calcium ion is surrounded by six chloride ions and vice versa, maximizing the electrostatic attraction and ensuring stability. This orderly arrangement contributes to the solid's characteristic properties, such as high melting and boiling points.
Does calcium chloride have a giant or simple structure?
Calcium chloride (CaCl₂) has a giant ionic structure. In this structure, calcium ions (Ca²⁺) and chloride ions (Cl⁻) are arranged in a three-dimensional lattice, held together by strong ionic bonds. This arrangement results in high melting and boiling points, characteristic of ionic compounds. Additionally, the giant structure contributes to its ability to conduct electricity when dissolved in water or molten.
What are the three elements that have known melting points than calcium?
Three elements with known melting points lower than calcium (which has a melting point of about 842 °C) are mercury (melting point -38.83 °C), francium (estimated melting point around 27 °C), and cesium (melting point 28.5 °C). These elements are either metals or metalloids that exist as solids at relatively low temperatures compared to calcium.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
What are the melting and boiling points of table salt?
The melting point of sodium chloride is 801 0C. The boiling point of sodium chloride is 1 413 0C.
