Answer:

Without a doubt, Africa is one of the most blessed continents on our planet in terms of both natural and human resources. So what are the causes of underdevelopment in Africa and possible solutions? The second most populous continent has an abundance of highly valuable minerals. It is therefore quite surprising that Africa is so backward when compared to most other continents. The reasons for this underdevelopment of Africa are varied hence it is important to outline as many of them as possible.

Compound X has a molar mass of 266.64 g/mol and the following composition: aluminum 20.24% chlorine 79.76% Write the molecular f
N76 [4]

Answer:

Explanation:

Assume we have 100g of this substance. That means we would have 20.24g of Cl and 79.76g of Al. Now we can find how many moles of each we have:

\frac{79.76 \:g}{35.45 \: g/mol} = 2.25 mol of chlorine

\frac{20.24 \: g}{26.98 \: g/mol} = 0.750 mol of Al.

To form a integer ratio, do 2.25/0.75 = 2.99999 ~= 3.

So the ratio is essentially Al : Cl => 1 : 3. To the compound is possibly AlCl_3.

However, it says it has a molar mass of 266.64 g/mol, and since AlCl3 has a molar mass of 133.32, it must be Al_2Cl_6.

Actually this molecule isn't exactly AlCl3 (which is ionic). Al2Cl6 forms a banana bond where Cl acts as a hapto-2 ligand. But that's a bit advanced. All you need to know is X = Al2Cl6

What is the electron configuration of a noble gas?
Debora [2.8K]

Answer:

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium's noble gas configuration becomes [Ne]3s1. That is the answer.

When a distance between gas particles increases, the volume of the gas increases true or false??​
Studentka2010 [4]

It is true that when a distance between gas particles increases, the volume of the gas will also increase.

Answer: Option A

<u>Explanation:</u>

The volume of any material can be the space occupied by any material. And the space required by any material to occupy a desired shape or size is determined by its bonding and distance between the particles making that material. If the particles which are soft and small can be compressed easily to occupy very small volume compared to compound made up of hard and large particles.

Along with this, the distance between the neighbouring particles also play a major role, as if we consider a laddo, we can compress it to small size by reducing the distance between neighbouring particles while we will not be able to compress the size or volume occupied by a table as we cannot reduce the distance of particle separation. Thus, it is true that if the distance between gas particles increased then the volume of gas particles will also increase.
