Nuclear Reactions Matching Solution
This solution matches the nuclear and chemical reactions provided in LIST-I with their correct classifications from LIST-II. It involves identifying fission, fusion, and chemical reactions.
Identifying Reaction Types
We examine each reaction in LIST-I:
- A. $^1_0n + ^{235}_{92}U \rightarrow ^{140}_{54}Xe + ^{94}_{38}Sr + 2^1_0n$
This reaction involves the splitting of a heavy nucleus ($^{235}U$) into two smaller nuclei ($^{140}Xe$, $^{94}Sr$) after bombardment with a neutron ($^1_0n$). This process is classified as nuclear fission. Therefore, A corresponds to III. Fission. - B. $2H_2+O_2\rightarrow 2H_2O$
This equation depicts the formation of water ($H_2O$) from hydrogen ($H_2$) and oxygen ($O_2$). It represents the rearrangement of atoms and the formation of new chemical bonds, which is a chemical reaction. Thus, B corresponds to I. Chemical reaction. - C. $^1_1H+^2_1H \rightarrow ^3_2He + ^1_0n$
This reaction shows two light nuclei, hydrogen ($^1_1H$) and deuterium ($^2_1H$), combining to form a heavier nucleus ($^3_2He$) and a neutron ($^1_0n$). This is an example of nuclear fusion. Fusion reactions typically release energy, hence matching with II. Fusion with +ve Q value. - D. $^1_1H+^1_1H \rightarrow ^2_1H+^0_1e$
Here, two protons ($^1_1H$) combine to form deuterium ($^2_1H$) and a positron ($^0_1e$). This is also a type of nuclear fusion. Based on the provided answer choices, this is categorized under IV. Fusion with -ve Q value.
