Mangrove swamps are found along the southern coasts of Florida. A mangrove swamp contains an ecosystem of many organisms living among the large roots of the mangrove trees. This food web shows some of the relationships in that ecosystem. According to the food web, which organism is a producer in the mangrove swamp?

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 !

wher is the rest of the question

the answer is c

tell me if wrong
