Which has a higher melting point MgO or CaO?

As Magnesium ion is smaller than the calcium ion, therefore the charge in case of Mg+2 ion is more than the Ca+2 ion. As a result, the lattice energy will be more in case MgO than CaO. Thus, because the lattice energy is more in MgO than in CaO, the melting point of MgO is higher than CaO.

Which out of CaO and MgO has high melting point and why?

Since, Mg2+ is smaller thanBa2+, therefore, MgO has the higher lattice energy and hence, has the higher melting point.

Does BEO have a high melting point?

4,672°F (2,578°C)
Beryllium oxide/Melting point

Which of the following compounds would you predict to have the highest melting point?

MgO
MgO has the highest melting point, by a large margin.

How do you determine melting point?

The melting point of an organic solid can be determined by introducing a tiny amount into a small capillary tube, attaching this to the stem of a thermometer centred in a heating bath, heating the bath slowly, and observing the temperatures at which melting begins and is complete.

What is the melting point of BEO?

How do you know which compound has the highest lattice energy?

The smallest ions will be able to get closest to each other. They will have the smallest distance between centres and will have the largest lattice energies. The smallest ions are at the top of the Periodic Table.

Which has a higher melting point NaCl or CAO?

Calcium oxide has a melting point of 2700∘C and sodium chloride has a melting point of 801 ∘C.

Which of the following compounds is predicted to have the highest boiling point?

Among the given options, (c) ethanol has the highest boiling point as it has the strongest intermolecular force of hydrogen bonding.

Does higher lattice energy mean higher melting point?

Higher lattice energies typically result in higher melting points and increased hardness because more thermal energy is needed to overcome the forces that hold the ions together.

Which has a higher melting point NAF or MgO?

Originally Answered: MgO is harder and has higher melting point than NaF . Explane? You must be very clever to ask such a question, because the explanation focuses on one particular principle: electrical attraction. First, NaF melts at 993C, and MgO melts at 2852C, significantly higher.

Why is beo the most acidic among all four oxides?

Hence basic character increases down the group. as the acidity of an element or the oxide/ hydroxide of an element increases along the period and decreases down the group, hence BeO will be the most acidic among all four oxides. The 4 Worst Blood Pressure Drugs.

Why is the lattice energy of MgCl2 higher than MgO?

MgCl2 consists of 3 ions in total, whereas MgO has 2 ions. as there are 2 Cl ions against one O ion the lattice energy is higher in case of MgCl2. Why is the lattice energy of MgO higher than NaF?
