Most plastics are made from oil or natural gas. One step in making plastics from these resources is called cracking. Cracking is

a process that breaks down bigger molecules into smaller ones. In one cracking reaction, ethane breaks down to become ethylene and hydrogen. During this process, thermal energy is absorbed from the surroundings and converted to chemical energy.

Why in oxidation of alkylbenzene no matter if alkyl group is big how it removed?​
Nezavi [6.7K]

Answer:

, no matter what the length of the alkyl group in the arene substrate, the product is always a one-carbon carboxyl group. Thus, the benzylic carbon atom has been oxidized and the term benzylic oxidation is appropriate. The term side-chain oxidation is also commonly used.

In alkylbenzenes, the carbon atom which is attached to the aromatic ring is particularly reactive. Reactions taking place at this carbon atom are said to occur at the benzylic position.

Benzylic halides undergo the typical reactions of alkyl halides; thus, you can expect to see such compounds used frequently in multistep syntheses.

Which of these is an example of light energy being transformed into chemical energy
Darya [45]

Answer:

An example of an energy transformation that occurs in the natural world is the process of photosynthesis. In the Sun, chemical energy transforms into light and thermal energy. Plants transform the Sun's light energy into chemical energy during the process of photosynthesis.

In which direction will the equilibrium shift if concentration of H 2 increases for the equation, CH 4 (g) + 2H 2 S(g) + energy
Serhud [2]

Answer:

The answer to the first question is B) left and the answer to the second question is A) right.

Explanation:

To solve these questions, we must remember that if a change is made to the system, the system will work to reduce that change. In these problems, if we add one reactant/product, the system will shift to use this compound and re-establish equilibrium.

For the first question, H2 is a product. If we add H2 to the system, the equilibrium will shift to the left to decrease the concentration of H2. The second question is the opposite since we are adding CH4 (a reactant). When CH4 is added, the system shifts to the right to decrease the concentration of CH4.
