<u>Explanation:</u>
When calcium hydroxide reacts with sulfur dioxide, it leads to the formation of calcium sulfate and water molecule.
The chemical equation for the reaction of calcium hydroxide and sulfur dioxide follows:
To calculate the entropy change of the reaction, we use the equation:
![\Delta S^o_{rxn}=\sum [n\times \Delta S^o_{products}]-\sum [n\times \Delta S^o_{reactants}]](https://tex.z-dn.net/?f=%5CDelta%20S%5Eo_%7Brxn%7D%3D%5Csum%20%5Bn%5Ctimes%20%5CDelta%20S%5Eo_%7Bproducts%7D%5D-%5Csum%20%5Bn%5Ctimes%20%5CDelta%20S%5Eo_%7Breactants%7D%5D)
For the given reaction:
![\Delta S^o_{rxn}=[(1\times \Delta S^o_{CaSO_3(s)})+(1\times \Delta S^o_{H_2O(l)})]-[(1\times \Delta S^o_{Ca(OH)_2(s)})+(1\times \Delta S^o_{SO_2(g)})]](https://tex.z-dn.net/?f=%5CDelta%20S%5Eo_%7Brxn%7D%3D%5B%281%5Ctimes%20%5CDelta%20S%5Eo_%7BCaSO_3%28s%29%7D%29%2B%281%5Ctimes%20%5CDelta%20S%5Eo_%7BH_2O%28l%29%7D%29%5D-%5B%281%5Ctimes%20%5CDelta%20S%5Eo_%7BCa%28OH%29_2%28s%29%7D%29%2B%281%5Ctimes%20%5CDelta%20S%5Eo_%7BSO_2%28g%29%7D%29%5D)
Taking the standard entropy change values:
Putting values in above equation, we get:
![\Delta S^o_{rxn}=[(1\times (101.4))+(1\times (69.9))]-[(1\times (83.4))+(1\times (248.5))]\\\\\Delta S^o_{rxn}=-160.6J/K](https://tex.z-dn.net/?f=%5CDelta%20S%5Eo_%7Brxn%7D%3D%5B%281%5Ctimes%20%28101.4%29%29%2B%281%5Ctimes%20%2869.9%29%29%5D-%5B%281%5Ctimes%20%2883.4%29%29%2B%281%5Ctimes%20%28248.5%29%29%5D%5C%5C%5C%5C%5CDelta%20S%5Eo_%7Brxn%7D%3D-160.6J%2FK)
Hence, the balanced chemical equation is written above and for the reaction is -160.6 J/K
A difference between plant cells and animal cells is that most animal cells are found whereas most plant cells are rectangular. Plant cells have rigid cell wall that surrounds the cell membrane.animals do not have a cell wall
Answer:
The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles).
The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart.
As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
The speed of spreading affects the shape of a ridge – slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes.

Answer:
Baking soda and vinegar react chemically because one is a base and the other is an acid. Baking soda is a basic compound called sodium bicarbonate. Vinegar is a diluted solution that contains acetic acid. ... The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate.
