A solution is usualy a diluted liquid that cleans for example bleach solution.
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 is: the average atomic mass 217.606 amu.
Ar₁= 203.973 amu; the average atomic mass of isotope.
Ar₂ = 205.9745 amu.
Ar₃ = 206.9745 amu.
Ar₄ = 207.9766 amu.
ω₁ = 1.40% = 0.014; mass percentage of isotope.
ω₂ = 24.10% = 0.241.
ω₃ = 22.10% = 0.221.
ω₄ = 57.40% = 0.574.
Ar = Ar₁ · ω₁+ Ar₂ · ω₂ + Ar₃ · ω₃ + Ar₄ · ω₄.
Ar = 203.973 amu · 0.014 + 205.9745 amu · 0.241 + 206.9745 amu · 0.221 + 207.9766 amu · 0.574.
Ar = 2.855 amu + 49.632 amu + 45.741 amu + 119.378 amu.
Ar = 217.606 amu.
But abundance of isotopes is greater than 100%.
It should be lead, with the fourth isotope weighs 207.9766 amu and an abundance of 52.40.
I would say #3 I’m sorry if it’s wrong tho
