Answer:
A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements.
Explanation:
If only one atom of a specific type is present, no subscript is used. For atoms that have two or more of a specific type of atom present, a subscript is written after the symbol for that atom
Answer:
The reactant particles have a greater average kinetic energy.
A smaller fraction of the reactant particles have energy greater than the Ea.
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:- Water is an electronegative molecule.
Explanation:
A molecule cannot be electronegative. Rather the atoms in a molecule may be electronegative. This first statement does not account for the hydrogen bonding in water at all because it is incorrect. However, the other statements in the question sheds more light on the nature of hydrogen bonding in water molecule.
