Answer : The correct option is, (2) Fission reaction.
Explanation :
- Fission reaction : This is a type of nuclear reaction in which the splitting of bigger nuclei into two smaller nuclei takes place. During this process, the large amount of energy is released.
- Redox reaction : This is an oxidation-reduction reaction in which the electrons transferred between the two molecules.
- Substitution reaction : In this reaction, one functional group is replaced by the another functional group in a chemical compound.
- Neutralization reaction : In this reaction, the acid and base react to give water and a salt.
Redox reaction, substitution reaction and neutralization reaction are the chemical reactions in which the heat releases when the chemical bonds are breaking and forming.
Therefore, the greatest amount of energy released per gram of reactants occurs during the fission reaction.
Answer:
oxygen
Explanation:
pls mark me brainliest right
The double and triple bond present in the molecule determines the shape of the molecule because the strength of the bond may tend to allow the bending in the molecule thus, revealing a different orientation. An example of this is sulfur dioxide (SO₂) which is a trigonal planar.
Answer:
See explanation
Explanation:
If heat is given out in a reaction, then that reaction is exothermic. If heat is absorbed in a reaction, then that reaction is endothermic.
Hence, if heat is given out, the reaction is exothermic. The heat given out does work on the surrounding thus the laws of conservation of energy are obeyed.
B but im not sure if im 100% correcr
