Answer:

Only Reaction 1

Explanation:

In reaction 1, there is a change in state from solid to liquid. Hence, there is an increase in number of ways particles and their energies could be arranged. As a result, entropy increases.

In reaction 2, there is a decrease in amount of gas particles (4 mol to 2 mol). Hence there is a decrease in the number of ways particles and their energies could be arranged. As a result entropy decreases

Which phase change represents a decrease in entropy?(1) solid to liquid (3) liquid to gas(2) gas to liquid (4) solid to gas
emmainna [20.7K]

Answer : The correct option is, (2) gas to liquid

Explanation :

Entropy : It is defined as the measurement of randomness or disorderedness in a system.

The order of entropy will be,

As we are moving from solid state to liquid state to gaseous state, the entropy will be increases due to the increase in the disorderedness.

As we are moving from gaseous state to liquid state to solid state, the entropy will be decreases due to the decrease in the disorderedness.

In option 1, 3 and 4, the entropy increases. while in option 2, the entropy decreases.

Hence, the correct option is, (2) gas to liquid

Covert 32 ft/sec^2 to m/min^2
igor_vitrenko [27]

Answer:

Explanation:

585.2 meters per minute in 32 feet per second To convert any value in feet per second to meters per minute, just multiply the value in feet per second by the conversion factor 18.288. So, 32 feet per second times 18.288 is equal to 585.2 m/min.

How many moles of O2 would be needed to produce 3.2 moles Fe2O3?
antiseptic1488 [7]

Answer:

0.533 mol O2

Explanation:

4 Fe3O4 + O2 -> 6 Fe2O3

1 mol O2  -> 6 mol Fe2O3

           x   -> 3.2 mol Fe2O3

x = (3.2 mol Fe2O3 * 1 mol O2)/ 6 mol Fe2O3

x= 0.533 mol O2

What happens to the intensity of light emitted from stars the further away the star is from us?
Nataly_w [17]

Answer: stars vary in their effective temperature and colour. A hot star radiates more energy per second per metre surface area than a cooler star. Does this then mean that a hot star is going to appear brighter to us than a cooler one? The answer to this actually depends on a few factors
