Which two electron configurations represent elements that would have similar chemical properties? (1) 1s22s22p4 (2) 1s22s22p5 (3

Anton [14]

Answer: Two electron configurations of elements that would have similar chemical properties are (2) and (4).

Explanation:

(1) $1s^22s^22p^4$

(2) $1s^22s^22p^5$

(3) $[Ar]4s^23d^5$

(4) $[Ar]4s^23d^{10}^4p^5$

Valence electrons : These are the electrons present in last principal quantum number of an atom of the element.

Two electron configurations represent elements that would have similar chemical properties are (2) and (4). This is because number of valence electrons present in both of them are same that is seven valence electrons . Also valence electrons of both the elements are present in p-orbital which means that they both belongs to same group in a periodic table. The members of same group in a periodic table have similar chemical properties.

11. 2073 Set D Q.No. 1 Ammonia molecule has got trigonal

Nikolay [14]

Answer:

See explanation

Explanation:

I know that we usually associate the sp3 hybridization to the tetrahedral shape. This is common in molecules such as CH4. So it may sound somewhat strange that NH3 molecule has an sp3 hybridized nitrogen atom and a trigonal pyramidal geometry.

Let us recall that the central nitrogen atom in NH3 has a lone pair of electrons. These lone pairs causes more repulsion than bond pairs. As a result of the presence of this lone pair, the bond angle in the NH3 molecule is distorted away from the expected 109.7 degrees in tetrahedral geometry and the bonding groups are now arranged in a trigonal pyramidal geometry(with bond angle less than 109.7 degrees) to minimize electron pair repulsions.

Identify the bronsted-lowry acid and the bronsted-lowry base in this reaction on the left side of each of the following equation

Dahasolnce [82]

<u>Answer:</u> $NH_4^+$ is an acid, $CN^-$ is a base, $NH_3$ is conjugate base and $HCN$ is conjugate acid

<u>Explanation:</u>

According to Bronsted and Lowry's theory:

An acid is defined as a proton donor while a base is defined as a proton acceptor.

In a chemical reaction, an acid loses a proton to form a conjugate base while a base accepts a proton to form conjugate acid.

For the given chemical reaction:

$NH_4^+(aq)+CN^-(aq)\rightleftharpoons HCN(aq)+NH_3(aq)$

$NH_4^+$ is losing a proton thus it is an acid to form $NH_3$ which is its conjugate base

$CN^-$ is gaining a proton thus it is a base to form $HCN$ which is its conjugate acid

Hence, $NH_4^+$ is an acid, $CN^-$ is a base, $NH_3$ is conjugate base and $HCN$ is conjugate acid
