What will be the answee for the quistion <br>solve for x 2x=1
Nadusha1986 [10]
Your answer is x= 1/2, this is because to get the x alone you need to move the 2 so you divide 2x by to and you have to do the same to the other side so 1/2, and you get x=1/2

Write the chemical equation that represents the process of lattice energy for the case of nacl.
faust18 [17]

Answer: Na^+(g)+Cl^-(g)\rightarrow NaCl(s),\Delta H_{Lattice}=-786kJ/mol

Explanation:

Lattice energy : It is defined energy released when ions combine together in a gaseous phase to form a compound. it is energy possessed by the crystal lattice of a compound. Denoted by symbol \Delta H_{Lattice}.

\Delta H_{Lattice}=positive , energy is absorbed while forming of the lattice

\Delta H_{Lattice}=negative, energy is release while forming of the lattice

Na^+(g)+Cl^-(g)\rightarrow NaCl(s),\Delta H_{Lattice}=-786kJ/mol

One mole of sodium ion when combines with one mole chloride ion release  786 kJ of energy.
