Answer:
IV
Explanation:
Entropy is a measure of the degree of disorderliness in a particular molecule. What we are saying is that randomization plays an important role in the quest for determining a molecule at a point of disorderliness.
Now let us look at the answer choices.
N2 is a gas and is expected to have a high amount of degree of disorderliness.
SiO2 although is at the absolute zero temperature which is supposed to necessitate a low entropy amount, the fact that it is not ordered I.e amorphous confers a degree of disorderliness in its molecule.
NaCl although perfectly ordered is not at the absolute zero and hence cannot exhibit the needed degree of disorderliness.
Na is our answer choice because it meets the two criteria needed for zero entropy. Firstly, it is of considerable orderliness and hence, entropy isn’t expected in its molecule. Also, it has no disturbance in the case of temperature as it is at absolute zero.
Answer:
False, False, True, True, False, True
Explanation:
- Mixtures have components that are always in fixed ratios. FALSE. The ratio of components in a mixture is variable
- Compounds can only be separated physically. FALSE. Compounds can only be separated chemically.
- The components of a mixture keep their unique properties. TRUE.
-
Mixtures can be physically separated. TRUE.
- Mixtures are pure substances. FALSE. Mixtures are formed by a mixture of 2 or more pure substances, not bonded chemically.
- Compounds are pure substances. TRUE.
Answer:
Ionic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding
