Identify whether each reaction represents a chemical reaction or a nuclear reaction by filling in the blank with the word ‘chemi
valkas [14]
A chemical reaction is defined as the reaction between two or more substances that produces new substances/compounds.

On the other hand, a nuclear reaction is a reaction that alters the nucleus of a certain atom. This can be done either by splitting the nucleus or by joining this nucleus with another one.

Reaction 1:
Cl₂ + H₂ ............> 2 HCl
This is the combination of two elements to produce a new compound.
Therefore, this reaction is a chemical reaction

Reaction 2:
²₁H + ³₁H .........> ⁴₂H + ¹₀n
This is an alteration in the nucleus of a hydrogen atom by bonding it with another nucleus.
Therefore, this reaction is a nuclear reaction

Hope this helps :)

Answer:

c. form trihalomethanes with organic compounds

Explanation:

Chloramines are compounds which are the derivatives of organic amine and ammonia. The N-H bonds in these compounds have been replaced by the N-Cl bonds. There are mainly two types of chloramines and they are inorganic chloramines and organic chloramines. Generally, chloramines contain chlorine, can be used to sanitize and disinfect, are safer than free chlorine, and can also be used to treat wounds and skin surfaces. Therefore, the correct option is (c) because chloramines do not form trihalomethanes with organic compounds.
