Answers

The answer is D. Stars are formed from interstellar clouds because of the Law of Universal Gravitation. The interstellar clouds are termed as nebula. When other stars dies a supernova occurs then the gravity from this pushes matter into the clouds until it cannot overcome the gravitational pull and it collapses which heats matter up forming a star.

What name should be used for the ionic compound LiI?

Answers

What name should be used for the ionic compound LiI?

The name that should be used for the ionic compound LiI is Lithium iodide. When naming ionic compounds, you have to take into consideration pairing of two components. 

Answer: The given compound is named as lithium iodide.

Explanation:

LiI is an ionic compound because lithium is a metal and Iodine element is a non-metal.

We know that, a bond which is formed between a metal and a non-metal is always ionic in nature.

Ionic bond is formed when there is a complete transfer of electron from an electropositive element (a metal) to an electronegative element (non-metal).

The nomenclature of ionic compounds is given by:

  1. Positive ion is always written first.
  2. The negative ion is written next with a suffix added at the end of the negative ion. The suffix used is '-ide'.

Hence, the name given to LiI will be lithium iodide.

Given the balanced equation:F2 energy → F F
Which statement describes what occurs during
this reaction?
(1) Energy is absorbed as a bond is formed.
(2) Energy is absorbed as a bond is broken.
(3) Energy is released as a bond is formed.
(4) Energy is released as a bond is broken.

Answers

Answer: The correct option is 2.

Explanation: We are given in the question that Fluorine molecule is dissociating into two Fluorine atoms. Equation for the following is given by:

F_2+energy\rightarrow F+F

In a chemical reaction if the energy is written at the reactant side, the energy is being absorbed and if the energy is written at the product side, the energy is being released.

From the given chemical equation, the energy is written at the reactant side, so the energy is being absorbed by the reactants in order to break the bond between F_2 molecule to form 2 individual Fluorine atoms.

Hence, the correct option is 2.

(2) Energy is absorbed as a bond is broken is the correct answer.

The only way to emit IR photons is if there are empty electronic energy levels really close to the ground state (lowest energy level). True or False

Answers

Answer:

False. The statement is not entirely accurate.

Explanation:

Infrared (IR) photons can be emitted in various ways, not solely dependent on the presence of empty electronic energy levels close to the ground state. IR photons are typically associated with changes in molecular vibrational or rotational energy levels rather than electronic energy levels.

IR spectroscopy, for example, focuses on the interaction of IR radiation with molecules. When molecules undergo vibrational or rotational transitions, they can emit or absorb IR photons. These transitions are related to changes in the kinetic and potential energy of atoms within the molecule as they vibrate or rotate.

Electronic transitions, on the other hand, are responsible for phenomena like ultraviolet (UV) or visible light absorption and emission. In these cases, electrons move between electronic energy levels, which are typically at higher energy levels than the ground state. So, the emission of IR photons is not directly tied to electronic energy levels close to the ground state.

In summary, IR photon emission is primarily associated with vibrational and rotational transitions in molecules, and it is not contingent on the presence of empty electronic energy levels close to the ground state.
