Answer:
1200 mL
Explanation:
Given data
- Initial pressure (P₁): 600.0 mmHg
- Initial volume (V₁): 400.0 mL
- Final pressure (P₂): 200.0 mmHg
For a gaseous sample, there is an inverse relationship between the pressure and the volume. If we consider the gas as an ideal gas, we can find the final volume using Boyle's law.
Answer:
Na+, O, C, Na
(Na+ has more ionization energy and Na has less ionization energy)
Answer:
ΔH > O and ΔH > TΔS
Explanation:
When a reaction is non-spontaneous even though the standard entropy change of the reaction is large and positive the reason is the reaction is highly endothermic and dominates the term TΔS in the standard Gibbs free energy expression:
ΔG = ΔH-TΔS
Remember that for an endothermic reaction to be spontaneous ΔG < 0 and this can occur only if the term TΔS is greater than ΔH. This is not the case for quartz which requires a good quantity of energy to overcome its crystaline 3D lattice in which the oxygen are shared between 2 silicon atoms.

if the same solution would be equal:
=> 0.5 grams of Sodium chloride dissolved in 0.05 liters solution
=> 0.5 moles of sodium chloride dissolved in 0.05 liters solution
The answer is NO. They are not equal because 0.5 grams of sodium chloride is equivalent
to 10 moles of sodium chloride which makes 0.5 grams of sodium chloride mixed
with 0.05 liters of solution more concentrated than 0.5 moles of sodium
chloride dissolved in 0.05 liters of solution.
