Answer:

All the areas of chemistry work in an interdisciplinary way, that is, they work together and share new discoveries with each other in order to improve every day.

Explanation:

There are many areas in chemistry that apply new discoveries to useful applications for consumers such as:

- Pharmaceutical chemistry: it is one of the areas that has developed the most researches throughout history, studying, researching, and improving chemical compounds and substances that allow improving the life quality of people. In this area of chemistry it is very important to apply the latest discoveries on bacterias, viruses and other microorganisms, in order to develop medications, vaccines, specific treatments and antibiotics to prevent, cure and relieve diseases and pains. They also use the latest knowledge of science to develop hygiene and personal care products, cosmetics, among others.

- Food Chemistry: this area of chemistry studies and produces, without a doubt, one of the biggest products acquired by consumers: food. For all these products to reach consumers properly, they must carry out and maintain strict controls both in the formulation of the products, as well as in the packaging, preservation and transport of those, that’s why in this area of chemistry it is important to apply the new and better discoveries that allow food to be taken safely to consumers and maintaining their organoleptic characteristics (color, taste, texture and smell).

- Chemical Engineering: this area of chemistry allows to design the best production process so raw materials are transformed into a certain product, thus generating useful products for both industries and consumers. In this case the new discoveries help to improve the production processes, making the products increasingly safe and of better quality.

- Petrochemical: This area is responsible for developing petroleum products such as natural gas, and the fuels that make the means of transport can move. In addition, this type of chemical industry generates the largest amount of organic chemicals that are used in all other areas of chemistry, so their new discoveries are of great importance.

There are also areas of chemistry that although it does not produce a product that can be used directly by consumers, they conduct very important studies and researches that helps other areas of chemistry create new and better products useful for consumers, such as:

- Environmental Chemistry: carries out very important studies and research that allow us to know the impact (positive or negative) that human activities have on rivers, soils, oceans, glaciers and the atmosphere. This allows to produce more harmless and less toxic products for people, animals and the environment.

- Materials chemistry: carries out investigations of the properties of materials of all types that are used in the other areas of chemistry. Examples of materials are plastics, metals, building materials, polymers, etc. This allows other areas of chemistry to choose the best material that suits the product they want to produce.

Which of the following sign does not indicate that a chemical change has happened .
Sever21 [200]

Answer:

A.)

Explanation:

A change in state may seem like a chemical reaction, but it is actually a physical change. "A change in state" is basically saying that the appearance of whatever the item is, is taking a change physically. Whether this item was going through some examples of a physical change, which would be:

<em>melting (solid to liquid), evaporation (liquid to gas), condensation (gas to liquid), freezing (liquid to solid), deposition (gas to solid), and sublimation (solid to gas).</em>

A change in color, odor, taste, chemical compound, and temperature all represent a chemical reaction, because these are all things that are happening within the the item that is being given the product of a chemical change.

Think of it this way: <em>internal changes within the product: chemical. External changes within the product: physical.</em>

I hope this helps.

GREYUIT [131]

Answer:

n = 2.208x10¹⁸ photons

Explanation:

The energy of a photon( an elementary particle) is given by the equation:

E = nxhxf

Where n is the number of photons, h is plank constant (6,62x10⁻³⁴ J.s), and f is the frequency. Knowing that the power level is 0.120mW (1.2x10⁻⁴ W), the energy in J, for a time of 78 min (4680 s)

E = 1.2x10⁻⁴x4680 = 0.5616 J

The frequency of a photon is its velocity ( c= 3x10⁸ m/s) divided by its wavelength, which is 780 nm = 780x10⁻⁹ m

f = 3x10⁸/780x10⁻⁹

f = 3.846x10¹⁴ s⁻¹

Then, the number of photons is:

0.5616 = nx6,62x10⁻³⁴x3.846x10¹⁴

n = 2.208x10¹⁸ photons.
