Which method of sharing data best enables others to quickly see trends in the data? A.) taking photographs of subjects
B.) recording observations in tables
C.) writing descriptions of observations
D.) making graphs of quantitative results

Correct Answer is; D. Just took the test.

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 !

can you list the answers so i can answer

i wish i could but this one is weird give me abc and i can solve it.
