Calculate the change in entropy when 10.0 g of CO2 isothermally expands from a volume of 6.15 L to 11.5 L. Assume that the gas behaves ideally.

The change in entropy of the carbon dioxide is kilojoules per Kelvin.

Explanation:

By assuming that carbon dioxide behaves ideally, the change in entropy (), measured in kilojoules per Kelvin, is defined by the following expression:

(1)

Where:

- Mass of the gas, measured in kilograms.

- Isochoric specific heat of the gas, measured in kilojoules per kilogram-Kelvin.

, - Initial and final temperatures of the gas, measured in Kelvin.

, - Initial and final volumes of the gas, measured in liters.

- Ideal gas constant, measured in kilopascal-cubic meter per kilomole-Kelvin.

- Molar mass, measured in kilograms per kilomole.

If we know that , , , , and , then the change in entropy of the carbon dioxide is:

The change in entropy of the carbon dioxide is kilojoules per Kelvin.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
