Answer: B. endergonic, not spontaneous
Explanation:
Endergonic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and 
for the reaction comes out to be positive.
The Gibbs equation is:
= Gibb's free energy change
= enthalpy change
T = temperature
= entropy change
A reaction is non spontaneous when = Gibb's free energy change is positive
Thus the reaction has to be endergonic.
Answer:
Explosive, Propellant and Semiconductor
Explanation:
The volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.
Explanation:
The kinetic theory of gases is mostly based on Boyle's law. From the Boyle's law, the pressure experienced by any gas molecules is inversely proportional to volume of the gas molecules. Also this inverse relation is obeyed if and only if the number of moles and temperature of the gas molecules remained constant.
So,
So if there is a change in pressure then there will be inverse change in volume. That means if there is decrease in the pressure of gas molecules then there will be increase in the volume and vice versa.
So the Boyle's law is combined as 
As here the initial pressure or 
is 1 atm or 101.3 kPa and the initial volume is 478 mL. Similarly, the final pressure is 93.3 kPa and the final volume will be
So, the volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.
