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.

The particles move faster because heat causes the atoms to speed up and move farther from each other.
Answer: option <span>B.The total mass of A and C, which are carbon and oxygen, is equal to the mass of B, which is carbon dioxide.
</span>
Explanation:
1) The combustion of carbon is represented by the chemical equation:
C + O₂ → CO₂
2) The law of conservation of mass states that the mass of the products is equal to the mass of the reactants.
3) The reactants are C and O₂, while the product is CO₂.
4) The masses given are: A: 12 g, B: 44 g, and C: 32 g
Then, 12g + 32 g = 44 g, this is A + C = B.
Then, B represents the product, which is CO₂, whose molar mass is 44 g/mol.
Since, the molar mass of C is 12 g/mol, it is A; and since the molar mass of O₂ is 32, it is C.
Therefore, the answer is the option B.
