the resulting compound is Li+ -------- Cl- in a crystalline lattice structure.

so first choice is wrong as its not a double bond

third choice is wrong as its not a ball-and-stick

fourth choick is also wrong as its not a triple bond

correct ans is The chemical compound will have a network structure.

Answer:

The chemical compound will have a network structure.

Explanation:

Li loses one electron to form Li⁺ cation and Cl gains one electron to form Cl⁻ anion. Li⁺ and Cl⁻ experience an electrostatic force of attraction forming an ionic bond. LiCl forms a 3D array of alternating Li⁺ cation and Cl⁻ anion such that the opposite charges balance each other.

LiCl exists in a crystalline lattice, where each Li⁺ has a coordination number of 6, or Li⁺ is surrounded by 6 Cl⁻ ions. The lattice of LiCl is called face centered cubic.

For the reaction o(g) + o2(g) → o3(g) δh o = −107.2 kj/mol given that the bond enthalpy in o2(g) is 498.7 kj/mol, calculate the

Aneli [31]

The reaction;
O(g) +O2(g)→O3(g), ΔH = sum of bond enthalpy of reactants-sum of food enthalpy of products.
ΔH = ( bond enthalpy of O(g)+bond enthalpy of O2 (g) - bond enthalpy of O3(g)
-107.2 kJ/mol = O+487.7kJ/mol =O+487.7 kJ/mol +487.7kJ/mol =594.9 kJ/mol
Bond enthalpy (BE) of O3(g) is equals to 2× bond enthalpy of O3(g) because, O3(g) has two types of bonds from its lewis structure (0-0=0).
∴2BE of O3(g) = 594.9kJ/mol
Average bond enthalpy = 594.9kJ/mol/2
=297.45kJ/mol
∴ Averange bond enthalpy of O3(g) is 297.45kJ/mol.

Identify the classification of milk a aerosol b solid emulsion c solid aerosol d foam e emulsion

enot [183]

option (c) emulsion is the right answer

Emulsion is a classification of milk.

<h3>Describe an emulsion.</h3>

In physical chemistry, an emulsion is a combination of two or more liquids in which one of the liquids is present as microscopic or ultramicroscopic droplets dispersed throughout the other.

<h3>How is emulsion used?</h3>

Emulsions form as a result of the cleansing action of soaps.

(ii) The emulsification process is how lipids are broken down in the intestines.

(iii) Disinfectants and antiseptics combine with water to generate emulsions.

(iv) The emulsification technique is utilized to create medications.

<h3>How is an emulsion created?</h3>

When two immiscible liquids, such as oil and water, are stirred together with an emulsifier—which might be a protein, phospholipid, or even a nanoparticle—emulsion is created.

The active ingredient in some oral anesthetics used in sore throat sprays. what is the molar mass of phenol?

raketka [301]

Answer: Molecular mass of the phenol is 94g/mol.

Explanation:

Phenol is an active ingredient in some oral anesthetics used in sore throat sprays.It is used as anesthetics to cure minor sour throat pain , minor mouth irritations etc.

For Example : Cramex , Chloraseptic sprays contains phenol as an active ingredient.

Phenol has a molecular formula of $C_6H_5OH$

Molecular mass of the phenol = 6(mass of carbon)+5(mass of hydrogen)+1(mass of oxygen)+1(mass of hydrogen) = 6(12)+5(1)+1(16)+(1) = 94 g/mol

Which squirrel do you think is better suited for the environment, the gray one or the white one? and why

boyakko [2]

Answer:

The grey squirrel.
