Suggest a way that chemistry knowledge could you make decisions about a claim

Answer and explanation;

-Knowledge of chemistry allows the public to make informed decisions.

-Since chemistry is the basis of everything in life, knowing the basics allows us to make smarter decisions. With a knowledge of chemistry, one can form better opinions about the day’s news. An individual will be able to distinguish the truth from the lies in environmental reporting, and better understand the meaning of a chemical spill.

-One can even better decide what your opinion on public policy should be by using your own knowledge of science rather than trying to figure out which politician or pundit is the least untrustworthy.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
