LBr is ionic compound because k for potassium is metal which means it’s on the left side of the periodic table and Br which is bromine is a non metal which means is on the right side of the periodic table.
In Conclusion when a non metal and metal come together the are called ionic compound
Answer:
0.11
Explanation:
This equation is not balanced because there is an unequal amount of O's on both sides of the equation. The left hand side has 4 P's and the right hand side has 4 P's. So the P atoms are balanced. The left hand side has 2 O's and the right hand side has 10 O's.
To fix this unbalanced equation a 5 in front of the O2 on the left hand side is added to make 10 O's on both sides resulting in
P4 + 5O2 = 2P2O5
The equation is now balanced because there is an equal amount of substances on the left and the right hand side of the equation.
Dissolution and dissociation of aluminum chloride:
AlCl₃(s) → Al³⁺(aq) + 3Cl⁻(aq)
The cation of aluminum is hydrolyzed:
Al³⁺ + 2H₂O ⇄ AlOH²⁺ + H₃O⁺
AlOH²⁺ +2H₂O ⇄ Al(OH)₂⁺ + H₃O⁺
Al(OH)₂⁺ + 2H₂O ⇄ Al(OH)₃ + H₃O⁺
Answer:
ΔHf0=ΔHsub+IE+ΔHdiss+EA+U
ΔHf0=108+496+122−349−788=411kJ/mol
The enthalpy change in the formation of an ionic lattice from the gaseous isolated sodium and chloride ions is −788 kJ/mole. That enthalpy change, which corresponds to the reaction Na(g)+Cl(g)→NaCl(s), is called the lattice energy of the ionic crystal. Although the lattice energy is not directly measurable, there are various ways to estimate it from theoretical considerations and some experimental values. For all known ionic crystals, the lattice energy has a large negative value. It is ultimately the lattice energy of an ionic crystal which is responsible for the formation and stability of ionic crystal structures.
