Give the group number and general electron configuration of an element with each electron-dot symbol:
MatroZZZ [7]

The group number of (a) is VA(15) and electronic configuration is 1s2 2s2 2p3 . the group number of (b) is IVA(14) and the electronic configuration is 1s2 2s2 2p2 .

What is electronic configuration ?

it shows the distribution of electrons in the atomic orbitals .  

it follows a standard notation of s, p, d, f atomic orbitals in which electronic distribution of an atom occurs .

it has standard notation method as well as condensed electron configuration .

it is useful in determining the valency of an element .

it is useful in predicting the properties of a group of elements .

<h3>What is condensed electron configuration ?</h3>

It contains the symbol of the nearest , smaller noble gas in the square brackets and then the symbols of the occupied orbitals which contains valance electrons .

Example of condensed electron configuration is given by ,

in case of iron the electronic configuration is 1s2 2s2 2p6 3s2 4s2 3d6 .

Thus , the condensed electron configuration of iron is [Ar] 3d6 4s2 .

Calculate the initial rate for the formation of c at 25 ∘c, if [a]=0.50m and [b]=0.075m
Alenkinab [10]
Rate = k * [A]^2 * [B]^1 

<span>Use the data from any trial to calculate k. </span>

<span>k = (rate)/([A]^2 * [B]^1) </span>

<span>E.g., for Trial 1, we have </span>

<span>rate = 3.0×10−3 M/s </span>
<span>[A] = 0.50 M </span>
<span>[B] = 0.010 M </span>

<span>Plug those numbers in and crank out the answer. </span>

<span>Now with the calculated value of k, calculate the initial rate for [A] = 0.50 M and [B] = 0.075 M </span>

<span>rate = k * [A]^2 * [B]^1 </span>

<span>k = calculated value </span>
<span>[A] = 0.50 M </span>
<span>[B] = 0.075 M</span>

Which of the following gases experience the greatest degree of deviation from ideal behavior under high pressures and low temper
xz_007 [3.2K]

A) CH4

In general, methane reactions are difficult to control. Partial oxidation to methanol, for example, is a rather difficult reaction because the chemical reactions that occur continue to form carbon dioxide and water even though the amount of oxygen available is insufficient.

<h2>Further explanation </h2>

Methane is the simplest hydrocarbon in the form of gas with the chemical formula CH4. Pure methane does not smell, but if used for commercial purposes, a bit of sulfur is usually added to detect leaks that might occur.

Methane is a greenhouse gas. Methane is used in chemical industrial processes and can be transported as frozen liquids (liquefied natural gas, or LNG).

Methane is a major component of natural gas, around 87% of volume.

Methane is not toxic, but is highly flammable and can cause explosions when mixed with air.
