Plastic beads used in jewelry making are made of long molecules usually consisting of carbon, hydrogen, and oxygen. Compare the

bonding in these molecules to the bonding in gems. (typed answers recommended)

This question is requiring a comparison between the bonding in gems and plastic beads, which of course have different natures. Thus, we can conclude that bonding in gems usually ionic because they comprise metal-nonmetal compounds with large electronegativity differences, such as Al₂O₃.

On the other hand, bonding in plastics, in general, tends to be covalent because hydrogen, carbon and oxygen have way similar electronegativities.

<h3>Types of bonds:</h3><h3 />

In chemistry, the formation of chemical compounds require the appearance of forces able to held atoms together. These forces are called bonds and can be covalent, metallic or ionic depending on the bonding substances. For instance, compounds formed a nonmetal and a metal tend to be ionic, whereas substances formed by two nonmetals tend to be covalent.

In addition, the type of bond defines most of the properties the substance has, thus, ionic bonds lead to solid and molecularly well-defined crystal structures whereas covalent bonds lead to amorphous solids.

In such a way, since gems have gorgeous appearances and are way resistant to high pressures, shear and temperatures, we conclude they have ionic bonds formed between metals and nonmetals.

However, plastic, such as that in plastic beads, will have covalent bonds because it is easily deformed and it is not able to withstand high temperatures, pressures or mechanical shears.

Moreover, the nature of the bonding depends on the electronegativity, which is the tendency an atom has to attract electrons; for that reason, large electronegativity differences lead to the formation of ionic bonds (metals and nonmetals, distant in the periodic table) whereas small differences lead to covalent ones.

Dinitrogen pentoxide is used in the preparation of explosives. If 7.93 mol of
Tpy6a [65]

The volume of O₂ produced: 84.6 L

<h3>Further explanation</h3>

Given

7.93 mol of  dinitrogen pentoxide

T = 48 + 273 = 321 K

P = 125 kPa = 1,23365 atm

Required

Volume of O₂

Solution

Decomposition reaction of dinitrogen pentoxide

2N₂O₅(g)→4NO₂(g)+O₂ (g)

From the equation, mol ratio N₂O₅ : O₂ = 2 : 1, so mol O₂ :

= 0.5 x mol N₂O₅

= 0.5 x 7.93

= 3.965 moles

The volume of O₂ :

\tt V=\dfrac{nRT}{P}\\\\V=\dfrac{3.965\times 0.082\times 321}{1.23365}\\\\V=84.6~L

How many valence electrons are in the element gallium? explain how you determined the number.
Natasha2012 [34]

Answer:

three valence electrons

Explanation:

Gallium has three electrons in the outer energy level and therefore has three valence electrons. The identification of valence electrons is vital because the chemical behavior of an element is determined primarily by the arrangement of the electrons in the valence shell.
