Explain how burning coal to generate electricity is really just an energy conversion starting with solar energy from the Sun and

ending with turning on a light in your house.
Chemistry

GuDViN [60]4 years ago

Explanation:

Energy conversion in using coal to generate electricity:

   Solar energy → Chemical energy → Heat energy → Mechanical energy  → Electrical energy

Solar energy from the sun is used by plants in the process of photosynthesis to manufacture their food. This solar energy is used to produce glucose and other substances useful for the sustenance of the plant. The food and plant matter are made up of a lot carbon compounds that posses chemical energy. When plants dies, the matter is collected in an anoxic environment and shallow swamps where they are lithified to form coal.

In power plants, coal is pulverized into smaller bits and burnt to produce heat energy. The heat energy is used to heat water to produce steam. Turbines have been engineered to transform mechanical energy into electrical energy as they rotate when driven by steam from boilers.

Electrical energy is seen as light in our homes.

Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins. Note that
adelina 88 [10]

Answer:

The three-step synthesis of trans-2-pentene from acetylene is as follows.

<u>Step -1:</u> Formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkanes.

<u>Step -2:</u> Formation terminal alkyne to nonterminal alkynes.

<u>Step -3:</u> Formation of trans-pent - 2-pent-ene by reduction.

Explanation:

Synthesis of trans-pent-2-yne from ethyne takes place is mainly a three step synthesis which involves formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkane. Second step involves the further alkylation of terminal alkynes to higher order nonterminal alkynes and the third step involves the formation of trans-2-ene by dissolving reduction method.

The chemical reaction of each step of chemical reactions is as follows.
