Answer:

Radioactive isotopes are widely used in medical field

Explanation:

Radioactive isotopes are widely used in medical field.

Radiations emitted by radioactive isotopes or used to kill the microorganism in food and to increase the shelf life of food.

Cobalt-60 is used to treat the cancer.

Iodine-131 is used to check the activity of thyroid.

Technetium-99 also used for the thyroid.

Phosphorus-32 is used to detect the cancer specially in skin and eyes.

Xenon-133 is used for lungs imaging.

Au-198 is used to diagnose the liver disease.

Co-60 is used as gamma ray irradiation of tumor.

In industry radioactive isotopes are used to measure the thickness of materials.

What changes would occur at a molecular level if a liquid is placed in cool conditions?
Dafna1 [17]

Answer: Option (C) is the correct answer.

Explanation:

Movement of particles in a substance is responsible for change in state of the substance or matter.

This means that more is the motion of particles more will be their kinetic energy.  

Also, kinetic energy is directly proportional to temperature.  

                     K.E = \frac{3}{2}kT  

So, less is the temperature of an object or substance less will be be the motion of its particles. Therefore, molecules will come closer to each other and state of substance will change from liquid to solid.

Thus, we can conclude that the motion of the molecules would decrease at a molecular level if a liquid is placed in cool conditions.

Identify the single displacement reaction. C4H12 + 7O2 ⟶ 6H2O + 4CO2 2H2 + O2 ⟶ 2H2O Al2S3 ⟶ 2Al + 3S Cl2 + 2KBr ⟶ 2KCl + Br2
Varvara68 [4.7K]

Answer:- Cl_2+2KBr\rightarrow 2KCl+Br_2

Explanations:-  The first reaction is combustion reaction as the hydrocarbon is burned in presence of oxygen to give carbon dioxide and water.

Second reaction is the synthesis reaction as in general a synthesis reaction looks like:

A+B\rightarrow AB

Third reaction is the decomposition reaction as it looks opposite of synthesis reaction.

AB\rightarrow A+B

In general, a single displacement reaction looks like:

AB+C\rightarrow AC+B

Fourth reaction is single replacement reaction as bromine is replaced by chlorine.

So, the correct choice is the last reaction, Cl_2+2KBr\rightarrow 2KCl+Br_2 .
