What attractions have to be broken for an ionic compound to melt?
To melt an ionic compound, the attractions between the ions in the crystal lattice need to be overcome. This requires breaking the ionic bonds that hold the ions together in a fixed position. Heating the compound provides the energy needed to disrupt these attractions and allow the ions to move more freely, resulting in the melting of the ionic solid.
The ions Cr3 plus and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound?
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).
What information is needed to write a correct chemical formula to represent an ionic bonds?
To write the correct chemical formula for an ionic bond, you need the charges of the ions involved. The positive and negative charges must balance in the formula, with the positive charge from the cation equaling the negative charge from the anion. Additionally, you will need to determine the ratio of the ions to ensure neutrality in the compound.
An ionic compound is a compound that consist of molecules made of atoms that are covalently bonded?
The given statement is not either true or false consistently. An ionic compound can contain atoms that are covalently bonded, as in sulfate and nitrate salts, but it need not contain any such covalently bonded atoms.
Do ionic compounds need to contain metals?
No, an ionic compound can be made up of any two substances that split into ions when put in solution (dissolved). An example of a non-metallic ionic compound is ammonium nitrate (NH4N03). When dissolved in water it separates into an ammonium ion (+NH4) and a nitrate ion (NO3).Also, whenever an acid is dissolved in water an ionic compound is formed. for example when sulfuric acid is dissolved in water it forms hydroxyl sulphate ((H30)2SO4) which separates into hydroxyl (+H3O) and sulphate ions (-2SO4).

How are formula written for ternary ionic compound given their names?
To write the formula for a ternary ionic compound given its name, you need to determine the charges of the ions involved. The total positive charge from the cations must equal the total negative charge from the anions to create a neutral compound. Use the criss-cross method by swapping the numerical charges to become subscripts. Be sure to simplify the ratio of ions to its lowest whole numbers.
Need the compound name for Sodium and Bromine?
Sodium Bromide - ionic compound - NaBr.
Why do you need to balance the numbers in an ionic compound what does this do?
Balancing numbers in an ionic compound is necessary to ensure that the compound has a neutral overall charge. This is because the compound should have an equal number of positive and negative charges to be electrically neutral. Balancing ensures that the compound follows the law of conservation of charge.
Does It require more energy to melt one mole of an ionic compound than one mole of a molecular compound?
Yes, it generally requires more energy to melt one mole of an ionic compound compared to a molecular compound because ionic compounds have stronger electrostatic forces between ions that need to be overcome in order to melt them, while molecular compounds typically have weaker forces like dispersion forces or hydrogen bonding.
How do you count the number of ions in a equation?
To count the number of ions in an equation, first identify the ions present in each compound. Then, determine the number of each type of ion by looking at the subscripts in the chemical formula. Finally, multiply the number of ions by the coefficient (if present) to get the total number of ions in the equation.
The correct formula of an ionic compound containing Al3 plus and CO32?
The correct formula for an ionic compound containing Al3+ and CO32- is Al2(CO3)3. This is because aluminum has a 3+ charge, and carbonate has a 2- charge, so to balance the charges, you need two aluminum ions for every three carbonate ions.
