Answer:
ΔS° = - 47.2 J/mol.K
Explanation:
ΔS°= 4(S°mH3PO4) - 6(S°mH2O) - S°mP4O10
∴ S°mH2O(l) = 69.9 J/mol.K
∴ S°mP4O10 = 231 J/mol.K
∴ S°mH3PO4 = 150.8 J/mol.K
⇒ ΔS° = 4*(150.8) - 6*(69.9) - 231
⇒ ΔS° = - 47.2 J/mol.K

If a force is applied but nothing happens, then it means that the forces are balanced. Being at such state, <span>equal forces are acting on an object in opposite directions. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
Answer:
See below
Explanation:
A chemist preforms the following: Neutralizing nitric acid (HNO3) with soda ash (Na2CO3). This reaction will then create sodium nitrate and carbonic acid, which will then decompose into water (H20)
Entropy change is defined only along the path of an internally reversible process path.
<h3><u>What is Entropy Change </u>?</h3>
- Entropy is a measure of a thermodynamic system's overall level of disorder or non-uniformity. The thermal energy that a system was unable to use to perform work is known as entropy.
- Entropy Change is a phenomena that measures how disorder or randomness have changed inside a thermodynamic system.
- It has to do with how heat or enthalpy is converted during work. More unpredictability in a thermodynamic system indicates high entropy.
- Entropy is a state function, hence it is independent of the direction that the thermodynamic process takes.
- The rearranging of atoms and molecules from their initial state causes the change in entropy.
- This may result in a decrease or rise in the system's disorder or unpredictability, which will, in turn, result in a corresponding drop or increase in entropy.
