Answer:
- 1 mole of carbon disulfide gas at 273 K and 40 L
- 1 mol of chlorine gas at 273 K and 40 L
- 1 mol of neon gas at 273 K and 40 L
- 1 mol of neon gas at 273 K and 20 L
- 1/2 mol of neon gas at 273 K and 20 L
- 1/2 mol of neon gas at 100 K and 20 L
- 1/2 mol of liquid neon at 100 K
Explanation:
Entropy is the measure of disorder or randomness in a closed system. Its an extensive property of a thermodynamic system
The following points must be considered when ranking the systems according to their entropy:
- The entropy of gases are highest than liquids or solid. And entropy of liquid is higher than solid. That is because gas has more microstate thus have the highest entropy.
- Entropies of large complicated molecules are greater than those of smaller, simpler molecules. Because larger molecules have more disorder because of the greater number of ways they can be move around in three dimensional space.
- highest temperature and highest volume will lead to greatest entropy
- 1 mole of any substance will have greater entropy than 1/2 mole of that same substance
Answer: Option (c) is the correct answer.
Explanation:
Entropy is defined as the degree of randomness. This means that more is the number of collisions taking place between atoms of a substance more will be the randomness.
Therefore, more will be the entropy of substance. We cannot measure the entropy but we can measure the change in entropy of a substance.
A thermometer is a glass tube that contains a liquid column generally mercury, and it is usually used to measure the temperature of human body.
A calorimeter is a device or apparatus that is used in a chemical reaction to measure the amount of heat involved.
Therefore, we can conclude that the student can't measure entropy directly, only an entropy change.
The number 6.022 × 1023 indicating the number of atoms or molecules in a mole of any substance
Answer:
1.602 moles CO
Explanation:
To convert from liters to moles, divide by 22.4:
35.88 L / 22.4 = 1.602 moles CO
Answer is a
bacteria doesn't have any cellular function in the cell.
