Answer:

non-polar covalent bonds

this is when the electronegativity difference between the two non-metal atoms is very little to cause a partial charge (delta positive and delta negative; δ+ and δ-) on the atoms

Explain how understanding the way materials behave can allow scientists to design technology.
torisob [31]

Answer and Explanation:

Materials are generally categorized into four main groups: metals, polymers, ceramics, and composites. Here are major types of material properties. They include: Physical, Chemical, Thermal, Acoustical, Mechanical, Optical, Electrical and Magnetic. These properties influence the way materials behave under certain conditions and environment, it is these behavioral changes of materials that scientists exploits to create new and different technologies.

There has been a major impact on material science due to the rapid rate of scientific discovery and new technologies, giving scientists many more materials from which to choose for their products. Advent of these new materials have given place for smart new products or quality classic designs.

Making the right choice of material is a complex and also a difficult task considering the numerous physical, chemical, optical, electrical, magnetic, thermal, aesthetic, mechanical and other appropriate properties to consider. Also, environmental, ethical and moral issues surrounding the right choice of materials for use in any product, service or system for design also need to be considered.

Materials would be developed to have specific properties. The development of new materials allows designers to be able to create new products, thereby solving old problems in numerous new ways. For instance, the explosion of plastic materials after the second world war made it possible to create new products without using valuable metals.

It is therefore the understanding of these material's behaviors after series of laboratory and industrial experiments have been carried out on them that scientists would take advantage of in order to create new designs.

For example, materials with photochromicity behaviors, that is, ability to change colors when exposed to light, can be useful for creating sunglasses lenses that darkens as the sun brightens.

The behavior of the choice of material was understood first through series of experiments which then helped the scientists to design such kind of sunglasses.

How many total atoms are in 0.500 g of P2O5?
BabaBlast [244]
<span>1.49 x 10^22 atoms
 
First determine the molar mass of P2O5 Atomic mass of Phosphorus = 30.973762 Atomic mass of Oxygen = 15.999 Molar mass of P2O5 = 2 * 30.973762 + 5 * 15.999 = 141.9425 Now determine how many moles of P2O5 you have 0.500 / 141.9425 = 0.003523 Since there's a total of 7 atoms per molecule of P2O5, multiply the number of moles by 7 to get the number of moles of atoms you have. 7 * 0.003523 = 0.024661 Finally, multiply by avogadro's number (6.0221409 x 10^23) to get the total number of atoms. 0.024661 * 6.0221409 x 10^23 = 1.48512 x 10^22</span>

The Kw of water varies with temperature. Calculate the pH of water at 46⁰C with a Kw = 1.219 x 10-14. Show all calculations lead
stich3 [128]
Kw = 1.219x10⁻¹⁴

kw = [H⁺] x [OH⁻]

in water [H⁺] = [OH⁻] therefore:

[H⁺] = √ kw

[H⁺] = √ <span>1.219x10⁻¹⁴

[H</span>⁺] = 1.104x10⁻⁷

pH = - log [H⁺]

pH = - log [ <span>1.104x10⁻⁷ ]

pH = 6.95

hope this helps!</span>

If the number of atoms of each element in the products equals the number of atoms of each element in the reactant the equation i
Misha Larkins [42]

<u>Answer:</u> The correct answer is Option b.

<u>Explanation:</u>

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another. Every balanced chemical equation follows law of conservation of mass.

This also states that total number of atoms of each element on the reactant side must be equal to the total number of atoms of each element on product side.

From the above information, the correct answer is Option b.
