Can some one help me please? also happy holiday peeps! 1. How do different plant structures increase the chances for successful reproduction? Use evidence to support your answer.
2.Why might there be an advantage for flowers that attract only one type of pollinator and exclude others? What would be the disadvantage? Explain your reasoning.

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 !
