Select the correct empirical formula for each molecular formula given.
Neko [114]

Answer: CH2O

Explanation:

this formula is glucose, as you said the molecular formula is C6H12O6 because an actual molecule of glucose contains that many atoms of each element

an empirical formula is the simplest whole-number ratio of a formula (ex: 1-2-1)

What multiplicities are observed for the signals in the off-resonance decoupled 13c nmr spectrum of (2e)-3-chloro acrylaldehyde?
Flauer [41]

The multiplicities that are observed for the signals in the off-resonance decoupled 13c nmr spectrum of (2e)-3-chloro acrylaldehyde is a singlet, a triplet, and a quartet. The correct option is E.

<h3>What is off-resonance decoupling?</h3>

Off-resonance decoupling is a process of removing all hydrogen and carbon coupling from a signal except for the place which is near the nucleus or joined with the nucleus.

In NMR also, the coupling of hydrogen and carbon is removed except for the place near the nucleus.

Thus, the correct option is E) a singlet, a triplet, and a quartet.

what is the electrons, valence electrons, and electron shells number please answer all 3 questions (look at the picture)
MariettaO [177]

In picture one, there are four electrons, one valance electrons and two shells, in image two there are three electrons, one valance electrons and two shells whereas there are 13 electrons, three valance electrons and three shells.

<h3>What is Electrons, Valence Electrons, and Electron Shells Numbers?</h3>

<u>Electrons</u>:

An electron is a negatively charged particle which can be either bounded with to an atom. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.

<u>Valence Electrons:</u>

Valence electrons are those electrons which are present in outermost shell or in valence shell or energy level of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

<u>Electron Shells Numbers</u>:

Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.

So we can conclude that In picture one, there are four electrons, one valance electrons and two shells, in image two there are three electrons, one valance electrons and two shells whereas there are 13 electrons, three valance electrons and three shells.
