Answer:
![\Delta _RS=-287.6J/K](https://tex.z-dn.net/?f=%5CDelta%20_RS%3D-287.6J%2FK)
![\Delta _RS=972.4J/K](https://tex.z-dn.net/?f=%5CDelta%20_RS%3D972.4J%2FK)
Explanation:
Hello,
In this case, the entropy of reaction is computed via:
![\Delta _RS=\Sigma\nu_i S_i^0_{product}-\Sigma\nu_i S_i^0_{reactant}](https://tex.z-dn.net/?f=%5CDelta%20_RS%3D%5CSigma%5Cnu_i%20%20S_i%5E0_%7Bproduct%7D-%5CSigma%5Cnu_i%20%20S_i%5E0_%7Breactant%7D)
In such a way, for the given reactions, we find:
- 3NO2(g) + H2O(l) ⟶ NO(g) +2HNO3(l)
![\Delta _RS=2*146+210.65-69.940-3*239.9=-287.6J/K](https://tex.z-dn.net/?f=%5CDelta%20_RS%3D2%2A146%2B210.65-69.940-3%2A239.9%3D-287.6J%2FK)
- C6H12O6(s) + 6O2(g) LaTeX: \longrightarrow⟶ 6H2O(g) +6CO2(g)
![\Delta _RS=6*188.72+6*213.7-212.1-6*205.0=972.4J/K](https://tex.z-dn.net/?f=%5CDelta%20_RS%3D6%2A188.72%2B6%2A213.7-212.1-6%2A205.0%3D972.4J%2FK)
Best regards.

Explanation:
Making a list of chemical and physical properties of different substances, will makes the study of these substances easier. The physical properties like mass density volume of a substance helps in measuring and knowing the amount of substance taken for a certain use.
While Enlisting the chemical properties of certain substances we see which two substances can be mixed or are allowed to react to get some required substance just by looking at the list without performing a sample reaction to check every time.
Answer:
the students are pushing with equal force

Answer:
This is the correct option:
HSO4– + H2O → SO42– + H3O+
Explanation:
The hydrogen sulfate or bisulfate ion HSO₄⁻ can act as either an acid or a base in water solution. This is called amphoteric
It can act as an acid, because it release a proton:
HSO₄⁻ + H₂O ⇄ H₃O⁺ + SO₄⁻²
It can act as a base, because it accepts a proton:
HSO₄⁻ + H₂O ⇄ H₂SO₄ + SOH⁻
