Sort these isotopes by whether they are most likely to undergo fusion or fission.
Maslowich

Answer:

Uranium-233- fission

Plutonium-239- fission

Plutonium-241- fission

Hydrogen-3 fusion

Hydrogen-1 fusion

Helium-3 fusion

Explanation:

In nuclear fission, heavy nuclear disintegrate into smaller nuclei when bombarded with particles such as neutrons. Fission reaction is common among nuclei having a high atomic number such as plutonium and uranium.

Fusion occurs between two light nuclei such as hydrogen or helium. It involves the combination of two lighter elements to give a heavier element with the release of tremendous amount of energy.

What can you infer about aspirin’s ester group?
Reil [10]

Answer:

Option B, aspirin’s ester group provides greater digestibility to aspirin

Explanation:

Aspirin ester group has three parts

  1. carboxylic acid functional group (R-COOH)
  2. ester functional group (R-O-CO-R')
  3. aromatic group (benzene ring)

Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -

aspirin

(acetylsalicylic acid) + water → salicylic acid + acetic acid

(ethanoic acid)

Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.

The term "conservation of energy" means that the total amount of energy in a system isolated from the rest of the universe remai
il63 [147K]

Answer:

True

Explanation:

<u>The first law of thermodynamics</u> establishes a relationship between the internal energy of the system and the energy that it exchanges with the environment in the form of heat or work.

The first law of thermodynamics determines that the internal energy of a system increases when heat is transferred or work is done on it.

Like all the principles of thermodynamics, the first principle is based on systems in equilibrium.

On the other hand, it is likely that you have heard more than once that energy is neither created nor destroyed, only transformed. It is the general principle of energy conservation. Well, the first law of thermodynamics is the application to thermal processes of this principle.

The universe as a whole could be considered an isolated system, and therefore its total energy remains constant.
