What is lattice energy of Crcl3?
5396kJ/mol
Energy released when a salt is formed from a gasious ions?
lattice energy.
Is nabr a acid?
No, NaBr is a neutral salt.
What are three properties of a simple crystal lattice?
Exemples of properties: structure, cell dimensions, lattice energy.
How many grams of NaBr are contained in 75.0 mL of a 1.5 M NaBr solution?
Molarity = moles of solute/Liters of solution ( 75.0 ml = 0.075 Liters ) Get moles NaBr 1.5 M NaBr = moles NaBr/0.075 Liters = 0.1125 moles NaBr (102.89 grams/1 mole NaBr) = 11.575 grams NaBr ( call it 12 grams ) ----------------------------------------------------
Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?
The lattice energy of potassium bromide is more exothermic than the lattice energy of rubidium iodide because lattice energy is inversely proportional to atomic radius.
What is the lattice energy of a compound?
Ions release some amount of energy when they get together to form a lattice. If it is needed to be seperated into ions again, the same energy should be absorbed. The energy to break 1 mole of a lattice at the standard temperature and pressure is defined as the standard lattice energy. Using formulae, the lattice energy at any conditions can be found as the standard values are tabulated.
Electrostatic attraction between ions causes the release of what?
it releases lattice energy
What are factors affecting lattice energy?
Ionic Charge and Ionic Radius - the smaller the radius the greater the lattice energy
What factors affect lattice energy?
Ionic Charge and Ionic Radius - the smaller the radius the greater the lattice energy
What role does lattice energy play in forming an ionic compound?
what role does lattice energy play in forming an ionic compound?
What are the factors affecting lattice energy?
ionic charge and ionic radius; the smaller the ionic radius the greater the lattice energy
Does calcium oxide have a higher lattice energy than magnesium oxide?
Cao or CaS have a higher lattice energy
What is the lattice energy for potassium bromide?
The lattice energy for KCl is 715 kJ mol-1.
How does lattice energy change the size of the ion?
Lattice energy is directly related to the size of the ions bonded. Smaller ions generally have a more negative value for lattice energy because the nucleus is closer to and thus has more attraction for the valence electrons.
What is lattice energy of Crcl3?
5396kJ/mol
