Answer:

They all vibrate, but they all move differently.

Explanation:

Similarities: They all consist of particles and vibrate, just at different frequencies.

Differences: The particles in solids move slowly and vibrate. In liquids, they move a bit quicker and slide past one another. They will also take the shape of the container they're in. In gases, they move freely at high speeds and also taking the shape of the container.

Hope this helped! :)

What is the difference between Renewable Energy and Non renewable Energy? Which one is better for the environment and why? Also

goblinko [34]

Answer:

The difference between them is that renewable energy is something that can be used practically and not run out. Non-renewable energy has a limited supply.

Explanation:

Renewable energy is better for the environment as it is not something that takes millions of years to form, as some non-renewable energy sources are.

Yes. Compounds can have different properties than the elements that go into them.

EXAMPLE: water is a polar liquid, while pure hydrogen and pure oxygen are both nonpolar gasses.

Given the following values for the change in enthalpy (deltaH) and entropy (deltaS), which of the following processes can occur

Shtirlitz [24]

Answer:

Option A and B

Explanation:

(a) DeltaH = -84 kj mol-2 (-20 kcal mol-1), DeltaS = +125j mol-2K-1)(+30 cal mol-1 K-1)

Delta G = Delta H – T * DS

Substituting the given values, we get –

Delta G = -84 -298 *(125/1000) = -121.25 KJ/mol

Delta G is negative hence the process is spontaneous and will not violate the second law of thermodynamics

(b) DeltaH = -84 kj mol-2 (-20 kcal mol-1), DeltaS = -125j mol-2K-1)(-30 cal mol-1 K-1)

Delta G =-84 -298 *(-125/1000) = -46.75 KJ/mol

Delta G is negative hence the process is spontaneous and will not violate the second law of thermodynamics

Delta G = 84 -298 *(125/1000) = +46.75 KJ/mol

Delta G is positive hence the process is non-spontaneous and will violate the second law of thermodynamics

(d) DeltaH = +84 kj mol-2 (+20 kcal mol-1), DeltaS = +125j mol-2K-1)(-30 cal mol-1 K-1)

Delta G = 84 -298 *(-125/1000) = + 121.25 KJ/mol

Delta G is positive hence the process is non-spontaneous and will violate the second law of thermodynamics
