Answer is: <span>sp3 on nitrogen overlaps with 1s on hydrogen.
</span>Electron configuration for nitrogen: ₇<span>N 1s² 2s² 2p³.
</span>Electron configuration for hydrogen: ₁H 1s¹.
<span>The central atom in ammonia, nitrogen, is </span><span>sp3 </span>hybridized (<span>one </span>s<span> and three </span>p-orbitals<span> will combine for a four sp3 </span><span>hybridized orbitals), because sp3 orbitals have lower energy</span>.

Draw a Lewis structure for ketene, C2H2O , which has a carbon‑carbon double bond. Include all hydrogen atoms and show all unshar
Vladimir79 [104]

<u>Answer:</u> The lewis dot structure is attached below.

<u>Explanation:</u>

A Lewis dot structure is defined as the representation of atoms having electrons around the atom where electrons are represented as dots.

A ketene is an organic compound having general formula R′R″C=C=O, where R and R' are two different/same monovalent chemical groups.

The given chemical compound having formula C_2H_2O is represented as H_2-C=C=O.

Total number of unshared electrons = 4 (left on oxygen atom only)

The lewis dot structure of C_2H_2O is given in the image below.

If the half-life of hydrogen-3 is 11.8 years, after two half-lives the radioactivity of a sample will be reduced to one-half of
maw [93]

Answer:

False

Explanation:

Half life is the time period at which the concentration of the radioactive substance in decay reduced to half.

<u>Thus, if the hydrogen-3 has gone 2 half lives, it means that it has first reduced to its half and then again the half of what it was, i.e. 1/4</u>

Thus, after two successive half-lives, the concentration must be 1/4 of the initial concentration and hence, the statement is false.

what is a photoelectric?explain the terms ground state and excited state with the help of labelled diagram
brilliants [131]

Answer: Photoelectric is characterized by or involving the emission of electrons from a surface by the action of light.

Photoelectric effect is the emission of electrons when a radiation of frequency higher than the threshold frequency falls on the surface of an element. The substance which undergoes photoelectric effect is called as photoelectric.

Ground state is the state representing the lowest energy  state.

Excited state is the state which represents a high energy state.

An electron in ground state absorbs energy to move to the excited state.
