Given the parent compound, draw the mass spectrum fragment that is observed at m/z 77. Include any hydrogen atoms and the charge. Its 6 carbon ring with 3 double bonds and a Cl coming off the of it.
Answer:
Water and applesauce are examples of a Homogeneous Mixture
Chicken Noodle Soup and Soil with Water would be examples of a Heterogeneous Mixture.
Explanation:
Homogeneous Mixtures are mixtures that are the same throughout, i.e. it's just one substance. A good example of this is a glass of water, this is because it is all one solution <u><em>without any other visible</em></u><u> </u><u><em>different parts</em></u><em> </em>that will settle if left alone for a while. The same applies to the applesauce, it is one type of a mixture with nothing else added to it.
Hetergeneous Mixtures on the other hand <u><em>are different substances </em></u>added together. The noodles, soup and chicken, three different substances in one mixture. The soil and water mixture also applies, two substances which separate if left alone.

Here we have to get the reason for continues changing of the atomic model over the past 200 years.
The reason for changing the atomic model is-The results of further experimentation helped to revise and improve the model.
The development of atomic model occurred step-wise as given below-
1. Rutherford atomic model, which explained the result of electrical neutrality of atoms by discovering the nucleus of atom, but it cannot explain the stability of accelerated charge particle i.e. electron.
2. The concept of radiation was later explained by Planck's quantum theory.
3. After this Bohr introduce another concept of atomic model which can explain the stability of the electron and also a part of the spectrum of the atom, but it has the demerits on the fine structure of the atom and heavier elements.
4. Sommerfeld extended the Bohr's theory, which gave the light on the elliptical orbits of a certain orbit.
5. After this to explain the wave-particle duality of the electron, the wave mechanical concept was proposed by deBroglie's, which further extended to the uncertainty to localize the electron and its velocity at a time which is Heisenberg uncertainty principle.
6. Later the quantum mechanical approach to explain the atomic model Schrodinger proposed equation which effectively explain most of the phenomenon of the atoms.
Answer:
Yeast cell is different from an onion skin cell in that Yeast can reproduce by budding while onion skin cells do not reproduce by budding.
Explanation:
- Reproduction is one of the characteristics of living organisms. All living organisms undertake reproduction to give rise to new organisms.
- There are two major types of reproduction namely asexual and sexual reproduction.
- Asexual reproduction is a form of reproduction that does not involve the fusion of gametes among organisms. Examples of asexual reproduction are budding in yeast and vegetative propagation in plants such as onions.
- Sexual reproduction, on the other hand, involves the fusion of gametes from male and female organisms which results in the formation of an embryo that develops to the fetus which becomes the offspring.
- Therefore, we could say that yeast cells reproduce asexually through budding while onions reproduce asexually through vegetative propagation.
