1.Explore two more isotopes and how it is useful in our day to day life.
Daniel [21]

Answer: Isotopes are useful in particular scientific fields. Theoretical astrophysicists point out that several new particles lead to new knowledge.

Explanation:

  • When science reached the fact that chemical elements exist as a set of many different isotopes, it was the cornerstone in discovering the composition of atoms, but also the formation of modern knowledge about the understanding of chemical elements. The practical significance of the discovery above has importance in physics and physical and analytical chemistry. Also, thanks to isotopes, some diagnostic methods have been developed in specific sciences such as geology and archeology. By determining certain radioactive isotopes by means using these two sciences, it is possible to decide on the age of the individual samples.
  • Theoretical physics is a viral branch of science today. This is a relatively young scientific discipline, and one of the greatest minds in the history of Stephen Hawking belonged to this discipline. The development and study of the atomic structure are significant for this scientific discipline. Some scientists point out that a large number of particles will be experimentally discovered in the future, as the atom has been found. It will undoubtedly cause new knowledge and reach for humanity. Thus, throughout history, the development of experimental physics has revealed a large number of particles that, in addition to protons, neutrons, and electrons, are contained in atoms.

How do you solve this ??
ICE Princess25 [194]

Answer:

Option D. 400 mmHg

Explanation:

The following data were obtained from the question:

Mole of He (nHe) = 0.04 mole

Mole of Ne (nNe) = 0.06 mole

Total pressure = 10³ mmHg

Partial pressure of He =.?

Next, we shall determine the total number of mole in the reaction vessel.

This can be obtained as follow:

Mole of He (nHe) = 0.04 mole

Mole of Ne (nNe) = 0.06 mole

Total mole =?

Total mole = nHe + nNe

Total mole = 0.04 + 0.06

Total mole = 0.1

Next, we shall determine the mole fraction of He.

This can be obtained as follow:

Mole fraction = mole of gas /total mole

Mole of He (nHe) = 0.04 mole

Total mole = 0.1

Mole fraction of He =.?

Mole fraction of He = nHe/total mole

Mole fraction of He = 0.04/0.1

Mole fraction of He = 0.4

Finally, we shall determine the partial pressure of He as follow:

Partial pressure = mole fraction x total pressure

Mole fraction of He = 0.4

Total pressure = 10³ mmHg

Partial pressure of He =.?

Partial pressure of He = 0.4 x 10³

Partial pressure of He = 400 mmHg.

Therefore, the partial pressure of He is 400 mmHg.

A bottle of 2 moles of an ideal diatomic gas experiences a temperature increase of 50.0K at constant volume. (a) Find the increa
andre [41]

Answer:

Explanation:

a) For diatomic gas: Translational motion = 3 and rotational motion = 2

∴ Total (internal energy) = 3 + 2 = 5

b) Translational + Rotational + Vibrational = 3 + 2 + 1 = 6

c) Linear molecule  

i) Non linear molecule

ii)  Monatomic molecule

My teacher is grading this soon can someone help me ASAP!
Stolb23 [73]

10. You demonstrated the difference in density of the two objects. It is a physical property.

11. First calculate the density for all of them: density = mass/volume

Density:

A. 5/6 g/ml

B. 10/9 g/ml

C. 15/16 g/ml

D. 20/10 g/ml

If the density of the substance is higher than the density of the substance it is put in, then it will sink. So substances B and D will sink in water, as their densities are higher than 1 g/ml.

12. Ammonia weighs less than water does-- for example, the weight of 8 gallons of ammonia will be equivalent to the weight of 5 gallons of water.

Hope this helped!
