The equation for the lattice energy of NaCl is as follows;

\boxed{{\text{N}}{{\text{a}}^ + }\left(g\right)+{\text{C}}{{\text{l}}^ - }\left(g\right) \to {\text{NaCl}}\left(s\right)}

Further Explanation:

Lattice energy:

It is the amount of energy that is released when ions are combined to form an ionic compound or the energy required to break the ionic compound into its constituent gaseous ions. It cannot be measured directly and is denoted by {\mathbf{\Delta }}{{\mathbf{H}}_{{\mathbf{lattice}}}} . It can have positive as well as negative values.

Case I: Positive lattice energy

The value of lattice energy (\Delta }}{{\text{H}}_{{\text{lattice}}}}} \right)) comes out to be positive if the energy supplied to the system is more than that released during the reaction. In other words, {\Delta }}{{\text{H}}_{{\text{lattice}}}} is positive in case of endothermic reactions.

Case II: Negative lattice energy

The value of lattice energy (\Delta }}{{\text{H}}_{{\text{lattice}}}}} \right))  comes out to be negative if the energy released by the system is more than the energy supplied during the reaction. In other words, {{\Delta }}{{\text{H}}_{{\text{lattice}}}} is negative in case of exothermic reactions.

Lattice energy is used to determine the stability of ionic compounds. NaCl is an ionic compound formed by one {\text{N}}{{\text{a}}^ + } ion and one {\text{C}}{{\text{l}}^ - } ion. The value of its lattice energy ({\Delta }}{{\text{H}}_{{\text{lattice}}}}} \right))  is -787 kJ/mol. A high negative value of lattice energy indicates that the formation of NaCl is highly favored.

The equation for the lattice energy of NaCl is as follows;

{\text{N}}{{\text{a}}^ + }\left(g\right)+{\text{C}}{{\text{l}}^ - }\left(g\right)\to {\text{NaCl}}\left(s\right)

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.

dimaraw [331]

Answer:

I will need  six (6) bags of potting soil

Explanation:

Since you plan on planting in 10 pots and need 15 cups of potting soil per pot, the total amount of potting soil you need <em>(in cups)</em> is 10 X 15 = 150 cups of potting soil.

We have that a bag contains 25 sups. to get the number of bags needed, we have to divide 150 by 25. This will give us 150 / 25 = 6 bags.

Therefore, I will need  six (6) bags of potting soil
