What is the importance of chemistry?
(N/A) Chemistry is the branch of science that studies the composition,properties,and interactions of matter.
It plays a central role in science and is often intertwined with other disciplines like physics,biology,and geology.
Chemistry is essential for understanding chemical transformations in nature.
It has significant applications in daily life,such as understanding weather patterns,the functioning of the brain,and the operation of computers.
In medicine,chemistry has provided life-saving drugs like $Cisplatin$ and $Taxol$ for cancer therapy,and $AZT$ $(Azidothymidine)$ for $AIDS$ patients.
It also contributes to environmental protection by synthesizing safer alternatives to hazardous substances like $CFCs$ $(Chlorofluorocarbons)$.

$25 \ mL$ of $0.1 \ N \ NaOH$ solution neutralises $12.5 \ mL$ of $HCl$ solution. The amount of water needed to convert $500 \ mL$ of such $HCl$ solution to $0.1 \ N$ is (in $mL$)
When $400 \ mL$ of $0.2 \ M \ H_2SO_4$ is mixed with $600 \ mL$ of $0.1 \ M \ NaOH$, the heat evolved is $3.43 \ kJ$. If the specific heat of water is $4.18 \ J \ K^{-1} \ g^{-1}$, the rise in temperature of the final solution will be ........... $K$. (Assume the specific heat capacity of the final solution is the same as that of water)
