Answer:

  1. 1 mole of carbon disulfide gas at 273 K and 40 L
  2. 1 mol of chlorine gas at 273 K and 40 L
  3. 1 mol of neon gas at 273 K and 40 L
  4. 1 mol of neon gas at 273 K and 20 L
  5. 1/2 mol of neon gas at 273 K and 20 L
  6. 1/2 mol of neon gas at 100 K and 20 L
  7. 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:

  1. 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.
  2. 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.
  3. highest temperature and highest volume will lead to greatest entropy
  4. 1 mole of any substance will have greater entropy than 1/2 mole of that same substance

Ugo [173]

Answer:

The answer is "3.81041978"

Explanation:

\to 1 \ OZ= 28.349523125 \ grams\\\\

              =28.349523125\times {1000} \ miligrams\\\\= 28349. 5231  \ miligrams\\

In 1860 = 28349.5231 \ miligrams\\

\to In \$ \ 1 = \frac{28349.5231}{1860} \ \ miligrams\\

             = 15.2416791 \ miligrams

\ In \  1 \ quarter =  \$ \ 0.25

\to \$ \ 0.25 =  15.2416791  \times 0.25 \  miligrams\\

              = 3.81041978

The formula for molality---> m = moles solute/ Kg of solvent

the solute here is NH₃ because it's the one with less amount. which makes water the solvent.

1) let's convert the grams of NH₃ to moles using the molar mass

molar mass of NH₃= 14.0 + (3 x 1.01)= 17.03 g/ mol

15.0 g (1 mol/ 17.03 g)= 0.881 mol NH₃

2) let's convert the grams of water into kilograms (just divide by 1000)

250.0 g= 0.2500 kg

3) let's plug in the values into the molality formula

molality= mol/ Kg---> 0.881 mol/ 0.2500 kg= 3.52 m

What is the idea behid boyles law​
zavuch27 [327]

Answer:

Explanation:

For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.
