Which best describes why NH4+ can form an ionic bond with Cl–? Its outermost shell gains one or more electrons from Cl–.
Its positive charge is attracted to the negative charge of Cl–.
It has a negative charge that is spread over the entire ion.
It has a nitrogen atom that is strongly attracted to Cl–.

Its positive charge is attracted to the negative charge of Cl–.

Explanation:

The best description of why NH₄⁺ forms an ionic bond with Cl⁻ is that its positive charge is attracted to the negative charge of Cl⁻.

An ionic bond forms as a result of transfer of electrons. As a result the seemingly metal ion is attracted to the negative non-metal ion.

The electrostatic force of attraction between these ions is the ionic or electrovalent bond.

So, the attraction between these opposite charges will form the ionic bond.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

its first and third is your answer i did the qustion the fourth isnt right
