What do you need help with
B. Because there are 3 molecules in right and 2 molecules in the left, so entropy rises.
Answer:
This is wirtten all in one paragraph, because that is what the question asks.
There are five main type of reactions under which you can classify most chemical reactions. Those are: combination (also known as shythesis), decomposition, combustion, single replacement and double replacement. You know that it is a synthesis (combination) reactions when there are two reactants and one single product (the two reactants are combined to form one single product). When you have one single reactant and two or more products, it is a decomposition reaction (the one reactant decomposed). When oxygen is one of the reactants the reaction is a combustion. When ions are exchanged you are in front of replacement reactions: if it is one ion which is exchanged it is single replacement, and if there are two reactants and two products in which the ions are exchanged, then it is a double replacement reaction.
Answer: The correct option is, 2.
Explanation:
Nuclear fission: It is defined as the reactions in which a larger unstable nuclei breaks into two or more smaller stable nuclei.
Nuclear fusion: It is defined as the reaction where two smaller nuclei combine together to form a larger nuclei.
Option 1 & option 2 shows fusion reaction and option 3 & option 4 shows fission reaction.
In option 1, helium itself is forming but in option 2, element is heavier than forming which is, neon.
Hence, the correct option is 2.
