Answer:
A. Political Science
Explanation:
The answer is political science because law is simply not a science. Economics has more of a focus on studying human activities so that does not fit either.
Answer: Changes can result from new science observations, and you discover new things overtime, the more experiments we do, and the more data we collect, the better our scientific ideas become. Even when we have the right explanation, it takes time for those ideas to spread among scientists, and even longer for those ideas to spread among the public.

-(4x3.15) multiply and you get -12.6
PV=nRT to find the moles
n= (1.2)(48.5)/(.0821)(450)
once u have the moles of chlorine gas multiply the mols by 2
then by the molar mass of HCl
So what is your question?
