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.

What is the de Broglie wavelength (in meters) of a 45-g golf ball traveling at 72 m/s?
Cerrena [4.2K]

Answer: The de broglie wavelength is 2.037 \times 10^{-34} m.

Explanation:

Calculate  \lambda = \frac{h}{p}as follows.

          \lambda = \frac{h}{p}

where,

          h = plank's constant = 6.6 \times 10^{-34} m^{2} kg/s

         p = momentum = mass \times velocity

Putting the values in the formula as follows.

        \lambda = \frac{h}{mass \times velocity}

                               =  \frac {6.6 \times 10^{-34} m^{2} kg/s}{0.045 kg \times 72 m/s}                        

                               =  2.037 \times 10^{-34} m

Thus, the de broglie wavelength is 2.037 \times 10^{-34} m.

Does data from mass spectrometry indicate that modern scientists have made modifications to Dalton''s model? Justify.
Gelneren [198K]
John Dalton was a scientist who proposed that all matter consists of atoms. At this stage, no one had yet discovered neutrons and the nucleus. As a result, Dalton's model consisted of a single atom i.e. the atom was the smallest object. 
A mass spectrometer is an instrument that is able to see what is inside an atom. Scientists have been able to prove that the item is not the smallest object in the world. Atoms are made up of smaller objects called protons, neutrons and electrons. 
We can, therefore, safely conclude that data  from mass spectrometry has helped modern scientists to make modifications to Dalton's model. <span>

Two 10g blocks, one of copper and one of iron, were heated from 300 K to 400K (a temperature difference of 100 K).
12345 [234]

1) 385 J

2) 450 J

Explanation:

1)

The amount of energy that must be absorbed by a certain substance in order to increase its temperature by \Delta T is given by the equation:

Q=mC\Delta T

where

m is the mass of the substance

C is its specific heat capacity

\Delta T is the increase in temperature of the substance

For the block of copper in this problem, we have:

m = 10 g is the mass

C=0.385 J/gK is the specific heat capacity of copper

\Delta T=400-300 = 100 K is the change in temperature

So, the energy absorbed by the block of copper is

Q=(10)(0.385)(100)=385 J

2)

Similarly for the block of iron, the energy absorbed by the iron is given by

Q=mC\Delta T

where

m is the mass of the block of iron

C is its specific heat capacity of iron

\Delta T is the increase in temperature of the block

Here we have:

m = 10 g is the mass of the block

C=0.450 J/gK is the specific heat capacity of iron

\Delta T=400-300 = 100 K is the change in temperature

So, the energy absorbed by the block of iron is

Q=(10)(0.450)(100)=450 J

HELP ASAP!!!!!! I NEED HELP
Whitepunk [10]

The organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

<h3>What are organs?</h3>

Organs are a collection of tissues that are closely related and which perform a related function.

The role and function of the organs of the digestive system are as follows:

  • Pancreas - produces pancreatic juice which contain digestive enzymes
  • Liver - produces bile for the emulsification of fat
  • Stomach - serves as a temporary store of food and produces digestive juices
  • Small intestine - functions in food digestion
  • Large Intestine - helps to remove undigested food from the body

Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.
