Chemistry
1 answer:

Answer:

Option D. 1191.49 K

Explanation:

The following data were obtained from the question:

Change in enthalphy (ΔH) = 280 kJ/mol

Change in entropy (ΔS) = +235 J/Kmol

Temperature (T) =...?

Next, we shall express the enthalphy in joule (J). This is illustrated below:

1 KJ/mol = 1000 J/mol

Therefore, 280 kJ/mol = 280 x 1000 = 280000 J/mol

Therefore, 280 KJ/mol is equivalent to 280000 J/mol

Now, we can obtain the temperature at which the reaction was feasible as follow:

ΔS = ΔH/T

235 = 280000/ T

Cross multiply

235 x T = 280000

Divide both side by 235

T = 280000/235

T = 1191.49 K

Therefore, the temperature at which the reaction was feasible is 1191.49 K

What happens when gases change to plasma?
IgorLugansk [536]

Answer:. In the case of neon, it is electrical energy that pulls the electrons off.

explanation-Plasma can be made from a gas if a lot of energy is pushed into the gas. In the case of neon, it is electrical energy that pulls the electrons off. When it is time to become a gas again, just flip the neon light switch off. Without the electricity to energize the atoms, the neon plasma returns to its gaseous state.

The Lewis structure of which molecule requires resonance structures?A.) MgCl2B.) SiO2C.) SO2D.) OCl2
inna [77]

Answer:  C.) SO2

Explanation:  Sulfur Dioxide is the gaseous molecule which can show the resonance through lewis dot structure due to the presence of lone pairs of electrons present on all of the three atoms of the molecules. Moreover , Sulphur forms pie bond with the oxygen using p orbitals which forms a network of the conjugated system that help to elaborate the reason of the formation of the resonance structure.

Options (a), (b), and (d) cannot form resonating structures as they involve the formation of the chemical bonds through single sigma bond.
