Answer:
it's the science of chemicals and liquids!
Answer:
Following are the difference in homolytic and hetrolytic bond dissociation.
- Homolytic dissociation is referred as the amount of energy released during homolytic fission. Homolytic fission is known as the dissociation of chemical bond in two equal fragmentswhereas, Hetrolytic dissociation is referred as the amount of energy released during Hetrolytic fission. Hetrolytic fission is known as the dissociation of chemical bond in two unequal fragments.
- Homolytic fission gives one electron each to its fragments whereas Hetrolytic fissiongives two electron to one fragment and zero electron to other fragment.
Energy released during Homolytic fission is lower than the Hetrolytic fission as the electron distribution to its fragments is uniform in homolytic whereas electron distribution to its fragments is uniform in hetrolytic fission.
Thus bonds form in hetrolytic fission is more stronger than the the bonds formed in homolytic fission.
Hence, more energy is required to break the bonds of hetrolytic fission as compared to homolytic fission
Thus, homolytic dissociation energy of H-H (104 KJ/mol) is lower than its heterolytic bond dissociation energy (401 KJ/mol)

Explanation . Claim: How solar cells different from silicon. evidence-The most promising group of these new materials are called hybrid lead halide perovskites, which appear to promise a revolution in the field of solar energy.Pure crystalline silicon is a poor conductor of electricity as it is a semiconductor material at its core.In a solar cell, the layers are positioned next to each other and that way an electric field is created.Crystalline silicon cells are made of silicon atoms connected to one another to form a crystal lattice. This lattice provides an organized structure that makes conversion of light into electricity more efficient.Solar cells are made from silicon boules. These are polycrystalline structures that have the atomic structure of a single crystal. The most commonly used method for the creation of the boule is known as the Czochralski method.
Reasoning: Traditional crystalline solar cells are typically made of silicon. An organic solar cell uses carbon-based materials and organic electronics instead of silicon as a semiconductor to produce electricity from the sun. Organic cells are also sometimes referred to as “plastic solar cells” or “polymer solar cells” hybrid perovskites Libai Huang, assistant professor of chemistry at Purdue, says the new material, called a hybrid perovskites, would create solar cells thinner than conventional silicon solar cells, and is also flexible, cheap and easy to make.
