Answer:

The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .

Describe the energetics of covalent and ionic bond formation and breakage?

Luda [366]

Answer:

The strength of a covalent bond is measured by its bond dissociation energy, that is, the amount of energy required to break that particular bond in a mole of molecules. The enthalpy of a reaction can be estimated based on the energy input required to break bonds and the energy released when new bonds are formed.

A gas is found with an unknown volume at a pressure of 1.5 atm and a temperature of 325K If the pressure is raised to 1.2 atm, t

sergij07 [2.7K]

The initial volume of the gas is 39 L, option C is the correct answer

<h3>What is the combined Gas Law?</h3>

According to combined gas law,

PV= nRT

In the Combined Gas Law, if we change either one of the variables the others will also change.

Here , Pressure (P), volume (V), number of mole of gas (n), and temperature (T).

When the moles of the gas is constant , the above equation can be written as ,

$\rm\dfrac{P'V'}{T'} = \dfrac{PV}{T}$

The data given in the question is

P = 1.5 atm

V= ? ml

T=325 K

V'= 48 L

P'= 1.2 atm

T' =320 K

Substituting the values in the above formula

$\rm\dfrac{1.2\times\;48}{320} = \dfrac{1.5\;\times V}{325}$

$\rm\dfrac{1.2\times\;48}{320} = \dfrac{1.5\;\times V}{325}\\\\\\\;\;\;\;\;\;V= 39 \;L$

Therefore the initial volume of the gas is 39 L, option C is the correct answer
