The sulfur and nitrogen compounds in smog combine with water to form Acid Rain. Acid rain is harmful to the environment and infrastructure because of its aidic components.
ΔSsys and ΔSsurr both have values larger than 0.
<h3>Entropy Change: What Is It?</h3>
- Entropy change is a phenomena that measures the evolution of randomness or disorder in 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.
- Heat transport (delta Q) divided by temperature equals the change in entropy (delta S).
<h3>What causes variations in entropy?</h3>
- When a substance is divided into several pieces, entropy rises.
- Because the solute particles are split apart when a solution is generated, the dissolving process increases entropy.
- As the temperature rises, entropy increases.

Answer:water self-ionize to form an equilibrium system that has [h30+]=1.0x10^-7 M
Explanation:
Answer:
<h3>The answer is 0.75 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%20%5C%5C%20)
From the question
mass = 90 g
volume = 120 mL
We have
![density = \frac{90}{120} = \frac{9}{12} = \frac{3}{4} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B90%7D%7B120%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B12%7D%20%20%3D%20%20%5Cfrac%7B3%7D%7B4%7D%20%20%5C%5C%20)
We have the final answer as
<h3>0.75 g/mL</h3>
